Kai Havertz believes he has solved Chelsea's most baffling enigma after stealing the show again in the Champions League.
Three coaches at Stamford Bridge – Frank Lampard, Thomas Tuchel and now Graham Potter – have tried to work out the £72 million German forward's best position.
Havertz insists the best solution of all is to treat him as Chelsea's flexible friend who can play anywhere at the top end of the pitch. The 2021 Champions League final hero came alive again in his favourite competition with a spectacular winner against Salzburg to book the Blues' passage into this season's last 16 as group winners with a game to spare.
