Chelsea boss Thomas Tuchel has backed Timo Werner to improve his form and insists his team will improve next season.
Werner has scored just six goals in his debut Premier League campaign after being signed for £45million from RB Leipzig last summer.
The Germany international had a big reputation after impressing in the Bundesliga, but for whatever reason it's been a largely difficult season for him in England.
The Blues have been linked with a move for Borussia Dortmund superstar Erling Haaland this summer, but when Tuchel was asked about Werner, the German coach insisted the best is yet to come.
"You will not find one manager who will not add a 20-goal striker to his squad. I cannot have enough of them, if you can guarantee that," Tuchel said to Sky Sports.
"But this is what Chelsea bought, they bought Timo Werner and he is a 20/30-goal striker a year. Now he is struggling a little bit, for the first time in his career.
"I have known him since he was 17. He scored every year in youth football. When he was 16 he played under-18, when he was 17 he played under-19 and he never stopped scoring.
"In any transfer, there are risks of adaptations, change of country, change of mentality. It needs time. It's not a puzzle where you identify one piece and you go out and find the exact piece, it's more than that and that's why there is no rush and no panic."
Chelsea have been linked with a host of players ahead of the summer transfer window, including Haaland and former striker Romelu Lukaku.
But Tuchel has stressed that his side will improve regardless if they have a busy transfer window or not.
"First of all, the most important is Champions League football," he continued. "After that, we can talk about with whom we play Champions League football, but one thing is very, very clear, we will be stronger next year.
"If we play with the same squad, we will be stronger because I demand it of myself. I'm more experienced, we are more used to each other we know each other better.
"So, this is all set to the next step and to not stay on the same level. The guys are hungry, they have the mentality and the attitude that is needed to grow and to get better.
"That's why I am 100 per cent sure that even if we do absolutely nothing, we have a lot of players who have not reached that top level yet."
