Much was expected of Germany international Havertz after he arrived at Stamford Bridge from Bayer Leverkusen, where he scored 46 goals in 150 matches and became the youngster player to reach 100 Bundesliga appearances.
But the 21-year-old has largely underwhelmed in the Premier League, scoring just once in 18 appearances and failing to cement a spot in Chelsea’s starting XI.
Havertz started Thomas Tuchel’s first game in charge – a 0-0 draw with Wolves last week – but was then dropped to the bench for Sunday’s 2-0 victory over Burnley.
Former Premier League manager Sherwood does not believe Tuchel should be playing Havertz at this moment of time and described Chelsea’s summer signing as a ‘liability’.
He told Premier League productions: ‘It’s difficult to judge Tuchel after two games. The first game against Wolves was boring, even though they had a lot of possession.
‘They were better against Burnley and two of the wing-backs scored so he’s throwing them forward.
‘I still think he’s got selection problems. I think he was brought in to get the best out of the German boys, Timo Werner and Kai Havertz.
‘But at the moment you can’t play Kai Havertz. In my opinion, he’s a liability. He might be a good player in the future but at the moment they’re just carrying him.
‘I wouldn’t play Havertz but I think he might be under a little bit of pressure to play Havertz and to find a position for Timo Werner.’
Chelsea, who are currently seventh in the Premier League, face Jose Mourinho’s Tottenham on Thursday evening.
Discussing Havertz’s struggles last weekend, new Blues boss Tuchel said: ‘What I feel from him is a very friendly, intelligent and open guy, with a lot of potential and we will push him.
‘He seems to be like the guy that needs to be pushed, we will not stop it. For him, this league is perfect because he cannot rest.
‘He has so much potential that he has to be challenged physically also, it is not enough that he can rely on his endless talent.
‘In the end, the question is does he have this, can he show his teeth in the end when it gets tough and I was very happy on Wednesday, it was him that did almost the decisive header in the box against all the towers from Wolverhampton.
‘It would have been a nice goal but he did not hesitate and that is what I want to see from him, the rest will come because Kai can be a huge, huge part of this club.’
