Kai Havertz misses Chelsea's game with Rennes after with positive Covid-19 test

Frank Lampard has deployed Kai Havertz as a right winger, a number 10 and even - on one occasion against Liverpool - as a central striker so far.

Kai Havertz tested positive for Covid-19 and was left out of the Chelsea squad which beat Rennes 3-0 in the Champions League on Wednesday.

Havertz, 21, has scored once since a £71m move from Bayer Leverkusen.

The Germany international midfielder will now self-isolate away from the rest of the Chelsea squad.

Chelsea returned a number of positive Covid tests after their short break between the end of last season and the start of the new term.
