Huge boost for Chelsea as new marquee signing is reportedly available to face West Ham this weekend 

According to football.london, Chelsea have been handed a massive boost ahead of their clash with West Ham United this weekend. New signing Wesley Fofana could make his debut for the club.

The Blues endured a busy end to the transfer window, making some key signings. They signed Fofana on August 31 from Leicester City for £72 million. They also signed Pierre-Emerick Aubameyang from Barcelona for £10.8 million and Denis Zakaria on loan from Juventus on the deadline day.

The Frenchman's availability was in doubt as he joined the west London club just two days ago.

The Blues will go into their clash with West Ham on the back of a disappointing 2-1 defeat to Southampton in midweek at the St. Mary's Stadium. Tuchel's side lacked defensive solidity and were desperately short of ideas whilst going forward.

They have won just two of their five Premier League games this season and have conceded eight goals. Fofana's availability could help solve their defensive issues.

Despite costing just £12.1 million, Pierre-Emerick Aubameyang could prove to be one of Chelsea's most important signings this summer. Thomas Tuchel's side have suffered from a lack of goalscoring threat.

The club failed to sign replacements for Romelu Lukaku and Timo Werner, who joined Inter Milan on loan, and RB Leipzig permanently, respectively. Kai Havertz and Raheem Sterling have so far been deployed as No.9's in Chelsea's five league games.

The Gabon striker scored 68 goals in 128 Premier League games during his time with Arsenal. He then scored 11 goals in 17 La Liga games for Barcelona during the second half of last season.

The forward suffered a broken jaw during a violent robbery attack at his home in Barcelona and is set to be ruled out of action for a few weeks.
