With Hammers striker Andy Carroll struggling with yet another injury, boss Sam Allardyce moved for Sakho, who has scored 43 goals to help Metz win back-to-back promotions in the last two seasons.

Soccer Cleats for sale The 24-year-old agreed a four-year contract with the Premier League side and could feature in the squad for their opening game of the season against London rivals Tottenham at Upton Park on Saturday.

Nike Magista Opus for sale "This is a proud day to have signed for West Ham, I really love English football and I've dreamed of coming to play for one of the big English clubs. Today, West Ham have given me that opportunity and I didn't hesitate to grab it," Sakho told West Ham's website.

Sakho scored 19 goals in 33 league appearances to fire Metz to second place and promotion to Ligue 2 in 2012-13.

Nike Mercurial for sale Last season, Sakho continued his rise to prominence by banging in 20 goals in 36 appearances as Metz romped to the Ligue 2 title.

The striker's outstanding form saw him handed a senior international debut by Senegal in a friendly meeting with Burkina Faso on 21 May 2014.

Four days later, he netted his first goal for his country in a 3-1 win over Kosovo.

Adidas F50 For Sale Regardless, the defending Premier League champions have locked up their most dangerous scorer. With today’s new five-year deal, Agüero is committed to the club through the 2018-19 season, after which he’ll turn 31 years old.

“This club is special; the fans, the stadium, the staff, the atmosphere, the new facility we’re moving into – everything,” Agüero said, via the club’s website.

Adidas Battle pack for sale “We have enjoyed lots of success and some incredible moments but the overall vision for the future and where we are going are the reasons why I wanted to stay here,” Agüero explained, “to win trophies and to keep making history through my best years.”

Agüero joined Manchester City three years ago, with his 23 goals in 34 appearances helping the Citizens claim their first Premier League title. After dropping to 12 goals during the 2012-13 season, Agüero scored 17 last year, though injuries limited the former Atlético Madrid striker to 23 appearances – the first time in his career he failed to play in at least 30 league games.

Unfortunately for Agüero, the last two years have each set career lows in terms of minutes, with a player who averaged 2640 minutes in his first six European league seasons reduced to 1847 and 1538 in his last two. With fitness also a concern during this summer’s World Cup, Agüero has proved more injury prone with age.

Nike Magista Opus for sale It’s one of the few imperfections in the Argentine’s arsenal. When healthy, Agüero gives Manuel Pellegrini the elite goal-scorer he needs to keep City at the top of the table. With Luis Suárez gone, Agüero offers a strike rate that can rival any player in the Premier League.

The Corsicans are now coached by former France midfielder Claude Makelele, who gave up his position as Laurent Blanc's assistant at the Parc des Princes to become a coach in his own right.

Adidas F50 For Sale Makelele also finished his playing career as captain of PSG and his presence on the opposition bench adds extra intrigue to a game that carries real importance to the hosts after they kicked off the campaign with a 2-2 draw at Reims.

"I am very happy that things have turned out this way and I can't wait to be at the Parc des Princes," said Makelele of the prospect of returning to Paris after last week's 3-3 draw with Marseille, another of his old clubs.

Makelele's previous job means he knows exactly how PSG will set themselves up, but he played down Bastia's chances of recording a first ever win in this fixture.

Adidas Battle pack for sale PSG, who have now failed to win their opening game in any of the four seasons since the Qatari takeover in the capital, were dealt a blow on Monday when captain Thiago Silva suffered a hamstring injury in a 2-1 friendly victory against Napoli that will rule him out for several weeks.

soccer shoes for sale Blanc has been criticised for bringing Silva back so soon after he was afforded a long summer break, and he may now be tempted to give new recruit David Luiz a little longer to build up his fitness.

There are seven new coaches in Ligue 1 this season and the only one to lose on his debut was Leonardo Jardim, whose Monaco side were beaten 2-1 at home by Lorient despite seeing fit-again Radamel Falcao come off the bench and score a penalty.

They will look to bounce back at Bordeaux, whose new coach Willy Sagnol is a former Monaco player.

Nike Magista Opus for sale Lille go to promoted Caen on Friday in a game brought forward to help them prepare for the first leg of their Champions League play-off against Porto next Wednesday.

Elsewhere, Lyon travel to Toulouse on Saturday while Marcelo Bielsa's Marseille entertain Montpellier and Saint-Etienne take on Reims on Sunday.

With that out of the way, where does Liverpool stand before the Premier League kicks off? A marquee attacking player has yet to be signed, but Rodgers and Liverpool have made a few solid signings in attack and midfield that should help reinforce an already excellent squad. Rickie Lambert, while at an advanced age, brings a wealth of experience and goals to act as a backup to Daniel Sturridge. The club still, however, need to sign a big-name striker to either partner or compete with Sturridge on the front lines. Philippe Coutinho, Raheem Sterling, and the hard-working Jordan Henderson all return on the back of a great season for each, and will be the key to Liverpool’s success this time around. New signings Adam Lallana and Lazar Markovic should provide competition for those players and give Brendan Rodgers options off the bench. Steven Gerrard and Joe Allen had relatively good seasons last year, despite the former’s ill-timed mishap that all but sealed the title for Manchester City. Lucas Leiva’s injuries have made it hard for him to cement a place in the starting XI as of late, and the arrival of a young Emre Can won’t do the Brazilian any favors either. I expect to see Emre Can get some early chances to prove himself, and show why the club is obviously grooming him to take over for Gerrard in the coming years.

While it was Liverpool’s breathtaking attack that brought them to the threshold of the Premier League title, it was the club’s defense that bolted the door shut. A plethora of injuries kept Brendan Rodgers from having a consistent center back pairing, thus the back four never had the chance to achieve the chemistry needed for a successful defense. Ironically, Liverpool’s transfer business last summer consisted almost completely of defenders meant to solve this very problem. Mamadou Sakho was the only player to come out of that crop with any dignity left, and may indeed be a starter for the Reds alongside the excellent signing of former Southampton defender Dejan Lovren. The Croatian was phenomenal against Borussia Dortmund in the club’s final friendly, and could be the vocal, commanding leader that the back line hasn’t had since Jamie Carragher retired. The club’s senior fullbacks, Glen Johnson and Jose Enrique, have never been world-class, but they’ve basically “done the job” over the past couple seasons. Enrique is still coming off an injury that kept him out of the team most of last season, but academy product Jon Flanagan proved a more-than-adequate replacement. The signing of promising young left-back Alberto Moreno surely spells the end for Enrique, and should prod Flanagan to work even harder to replace the Spaniard. The club’s second fullback loan in as many seasons, Javier Manquillo looks to replace Glen Johnson, whose performances have failed to impress as of late.

Soccer Cleats for sale Pepe Reina, a club favorite whose destiny was sealed last summer before his loan to Napoli, finally made a permanent move to Bayern Munich. It’s rumored that another goalkeeper will be brought in to challenge Simon Mignolet, who Brendan Rodgers considers a long-term project. Mignolet has slowly adapted to Brendan Rodgers’ style, and will hope to win over skeptics this season.

Battle pack cleat Many pundits have already predicted that Liverpool will fall back instead of building on last season’s success. But the club is used to being seen as the underdog; nobody expected them to go from seventh to competing for the title last year. Whether or not the club does what everyone thinks they should–pick up a marquee signing like Falcao, Reus, or Shaqiri–the players the club already has have the talent to go just as far, if not further, than the team did last year. The key to Liverpool’s season will be creating chemistry from front to back, hopefully forming a structured and disciplined back line and a potent, lethal attack.
