Werner was signed by Lampard to score the goals needed to fire Chelsea to the Premier League title but has bagged just 10 league goals in two seasons. He was moved to a left-sided attacking role by Tuchel following the arrival of Romelu Lukaku last summer, but Sterling’s signing throws into doubt Werner’s future in that role.
The German could reprise his position as Chelsea’s centre-forward, but it was telling that Kai Havertz was preferred through the middle during Lukaku’s poor periods of form last season.
Sterling is poised to be announced as one of Chelsea’s first signings of the summer after posting an emotional goodbye to Man City supporters. The 27-year-old will bring much-needed goals to the Blues’ forward line.
Tuchel is also set to welcome defender Kalidou Koulibaly to Stamford Bridge, with Chelsea finally signing their long-term target from Napoli. Sterling’s former City team-mate Nathan Ake has also been linked with a return to Chelsea.
