Kai Havertz’s former manager at Bayer Leverkusen, Peter Bosz, says he cannot see how Frank Lampard is planning to utilise the playmaker.
Havertz arrived at Stamford Bridge in the summer for £70million but has managed just one Premier League goal in 15 appearances and currently finds himself out of favour.
Used primarily as a false-nine for Leverkusen, the 21-year-old was one of the stars of the Bundesliga last season, attracting interest from a host of top European clubs.
But he has struggled in his first season in England and Bosz claims Lampard’s management isn’t helping.
He told The Athletic: “As for Kai, I can see why Chelsea brought him in but I cannot yet see the exact idea Frank Lampard has for him.
“It’s really good that he protects him in the press, though. But in the end, you must deliver, you must score goals and make goals. For a €100 million transfer you must play, and he isn’t.”
In his defence, Havertz has been badly affected by coronavirus.
“It was like a very bad flu for me so I think now I know it is very bad for people. Before I sometimes thought, ‘OK it is not so bad’ but now I get it and I know for older people and people who had illnesses before it can be very bad,” Havertz said in December.
“We all have to look out for each other. To be honest, it was personally very hard.”
Before adding: “When you do nothing for two and half weeks and then you start training again, you feel like you have never played football before. For me it took two or three weeks to get back to 100 per cent.
“Now I have started three games and I’m feeling good. It takes a lot of time and it took around one and a half months for me to get back but now I think I am very fit again and can start to attack again.”
Havertz has started four successive Premier League games from the bench and hasn’t started since the 2-1 defeat at Wolves on December 15.
