Former Chelsea centre-back William Gallas has expressed his confusion over Graham Potter's tactics.
Potter replaced the sacked Thomas Tuchel in the Stamford Bridge dugout and took charge of his first game earlier this month, overseeing a 1-1 draw at home to Red Bull Salzburg in the Champions League.
And the 47-year-old made two particularly intriguing tactical decisions, deploying Raheem Sterling at left wing-back and Marc Cucurella as the left-sided centre-half in a back three.
Those choices baffled Gallas, as he explained in an interview with Genting Casino (via the Daily Star). The former France international – a member of Chelsea's first two Premier League title-winning teams – said:
"It's difficult for me to understand why he wants to experiment with something like this, especially in a Champions League game.
"You are playing at home and you put Cucurella as a centre-back (you have Fofana on the bench with Koulibaly, Chalobah on the bench...), and you put Sterling as a left wing-back? I don't understand."
The switch from centre-forward to wing-back didn't seem to affect Sterling too much: Chelsea's £47.5m summer arrival from Manchester City scored the game's opening goal.
That said, it remains to be seen how Potter will use him and Cucurella – who he coached at Brighton – in Saturday's trip to Crystal Palace, his first Premier League match as Blues boss.
