William Gallas revealed Benoit Badiashilegreatest weakness after chelsea signed him from Monaco during the January transfer window.
Badiashile arrived at Stamford Bridge in a £35m deal of the Ligue 1 club as the Blues spent over £300m on eight new faces.
The 21-year-old France international centre-back is likely to provide competition for fellow defender Wesley Fofana, who was signed for £75million in the summer.
Gallas backed Badiashile to ‘form a strong partnership’ with Thiago Silva but warned Blues fans of a key weakness in his game.
“Technically he’s really good,” Gallas said. Genting Casino. “He has a presence and is very calm with the ball at his feet.
“He has a good left foot and is very calm. All the ingredients are there [but] I want to see how he reacts to a physical challenge.
“When he has to go one-on-one with a good opponent. In Monaco, his weakness was his physique – he struggled against bigger opponents in France.
“We know in England that the Premier League is a lot more physical than League One, so we’ll have to see how he responds to that challenge.”
Asked about Chelsea’s spending spree since the summer, with the west London club having now splurged around £600million during the Todd Boehly era, Gallas added: “Chelsea are very behind other teams in the league at the moment.”
“I look at the club and I don’t know what they are doing, just buying, buying, buying players, handing out seven-year contracts like in American sport.
“I’ve never heard of a seven-year contract in England – that’s the style of the American owners.
“I think slowly, slowly, Todd Boelhy will understand that football is totally different from American football or American sports in general.
‘At the moment he has bought players but where are the results? They fired Tuchel and brought in Graham Potter, but they don’t have the results.
“They have made all the medical staff redundant, but on the face of it it would be concerning if they delivered better results.
“You have so many injured players at the club. Fofana is injured. Reece James was injured, came back and got injured again.
“It’s a big mess at Chelsea at the moment. What are they going to do with all these players they’ve signed? They’ve bought so many players.
“What will they do with the players they don’t want at the end of the season? They will try to sell them, but some players won’t want to go. What will they do then?
“If you want to compare Chelsea under Abramovich and under Boehly, you have to remember that Abramovich bought the club and the goal was to qualify for the Champions League.
“He was an owner who took his time. He learned the club mentality and also understood how football works in the UK – that’s what you have to do.
“Boehly came into the club and changed everything. Buy players, fire a coach, bring in Potter, fire the medical staff. It’s the owner’s responsibility and we’ll see what happens.
