Former Aston Villa ace Gabriel Agbonlahor has concerns about Chelsea record signing Enzo Fernandez.
The midfielder, who arrived on deadline day in January from Benfica, has struggled so far in the Premier League.
Despite the odd glimpse of his talent and ability, Fernandez has not imposed himself on games as the Blues are going through a miserable run of form.
Speaking on talkSPORT, Agbonlahor said: "I'm worried about the players' body language.
Havertz does nothing, he can't create as a 10, or hold up play as a 9.
"Sterling runs all game but doesn't get the ball.
Enzo, who's been incredible, looks annoyed at his teammates. There's just no connection between them."
