Former Chelsea star Cesc Fabregas believes Kai Havertz and Timo Werner will be different players next season.
The German duo struggled for consistency in their first season in English football, having both sealed big money moves from the Bundesliga last summer.
But Fabregas, now with Monaco, has claimed the duo will improve for the 2021/22 campaign.
He wrote in a column for the Daily Telegraph: "I watch every single Chelsea game, so I've followed the first seasons of the club's two big German signings, Kai Havertz and Timo Werner, very closely and I am convinced next season we will start to really see the best of them.
"As a midfielder who likes to make assists, I have played behind strikers before who are going through a bad time or suffering with their confidence.
"It's a bit of both that it can be frustrating that they miss chances, but I would also be thinking at some time Werner will score.
"The most important thing is that he keeps making the runs, that his timing is good, that he's not offside and with his speed he will always get chances.
"Players like Werner are so valuable nowadays because players want the ball at their feet a lot and, as a midfielder, you would like this type of player to run on to your passes.
"Football is so much about confidence and what's in your head and especially strikers who depend so much on scoring or not scoring. If they miss, it's when you need to support them the most."
"He told me that Havertz would usually struggle a little bit at the start of seasons to get going, but that once he gets a clear ride and is mentally good then he's a fantastic player.
"He didn't have to touch a lot of the ball, but he helped the team tick. He was not losing the ball, he made everyone else secure, he was creating stuff. And I think at the end of the season, he was very, very good.
"I saw that both Werner and Havertz scored for Germany in their last warm-up game, so, hopefully, they can have a good tournament and, definitely, I think we will see different players for Chelsea next season."
