Chelsea transfer target jets in after medical and races to prepare for West Ham game

French defender Wesley Fofana has completed his medical and flown back to London for his official unveiling.

Chelsea and Leicester finally agreed a fee in the region of £70m, according to the Athletic, and the defender is desperate to be involved against West Ham over the weekend.

The 21-year-old has signed a six year deal and will now add to the options manager Thomas Tuchel has at his disposal.

Fofana is seen as a rising star in France and England - and Leicester held on tight to get a maximum fee before letting him move to the London club.

The Blues are looking to build a brand-new back line after losing Antonio Rudiger and Andreas Christensen for free this summer.

Kalidou Koulibaly and Marc Cucurella have arrived while Thiago Silva and César Azpilicueta still form the basis of continuity in west London.

But there is no hiding from the fact the team needs fresh blood and huge investment if they are to challenge for the Premier League and the Champions League this season.

Chelsea have endured a difficult start to the campaign, losing two, drawing one and winning two of their opening five games of the Premier League season.

The defeat at Southampton was particularly disappointing as they took the lead through Raheem Sterling, his third goal since joining from Manchester City.

But the squad allowed Southampton to respond with goals from Romeo Lavia and Adam Armstrong.

After the defeat at St Mary’s manager Thomas Tuchel said his side needed to toughen up, as it was too easy to play against them.

He told BBC Match of the Day: ”It is too easy to put us off balance, to beat us, to confuse us.

“It is too easy. It happened against Leeds.

“We need to understand why and find solutions.

“We lose concentration, we lose our plan and lose consistency, it is too easy to beat us.”
