Sky Sports pundit Jamie Redknapp has slammed Jose Mourinho's tactics after Chelsea were beaten at home in the Champions League to FC Basel last night.
And Redknapp has said that if it wasn't for the fact that it is Mourinho, many would be questioning his tactics.
The ex-Liverpool star also believes that the Portuguese boss is unsure of his strongest team and is baffled by the regular omissions of Spaniard Juan Mata from the side.
Speaking on Sky Sports, Redknapp said: "If it wasn't Jose Mourinho, you'd probably be thinking 'what is this guy up to? What's their best system? What's their identity? How do they play?'
"I've seen him use so many players in different positions since the start of the season. I still can't believe he's not picking Juan Mata. When I think about Chelsea retaining the ball and people who are comfortable on it, Mata has to play.
"I just think at the moment there's no real system to the way that they play. Where's Andre Schurrle? Where's Kevin De Bruyne? I don't think Jose really knows what his best team is.
Redknapp also believes the Chelsea side are struggling to form a relationship with one another as Mourinho continues to rotate his side.
He continued by saying: "When you play football, it's about building relationships - be it centre-backs, midfielders, wide men, front men. At the moment, no-one seems to have any relationship with anyone because they don't know who he is going to play."
The Blues' defeat last night came off the back of a defeat at Everton as they made the worst start to a league campaign in the Roman Abramovich era.
Mourinho and his side will be desperate to rectify their recent results by defeating London rivals Fulham at Stamford Bridge this Saturday evening.
