Chelsea manager Thomas Tuchel has once again sought to explain Ben Chilwell's lack of playing time this season.
The Englishman was a mainstay in Chelsea's team last season, making 27 starts as the Blues won the Champions League and reached the FA Cup final.
He has however fallen down the pecking order for club and country, with Marcos Alonso replacing him at wing-back in the new season.
Tuchel has however urged the former Leicester man to keep training hard and be patient.
"He came from a Champions League win, and from 90 minutes and a strong performance, and had a good end of the season in general," Tuchel said on Tuesday.
"Then it was individually for him a tough Euros because there were chances I think where he thought he could have played, and he did not,"
"It was hard for him to totally relax and to get this personal disappointment, that he would never put out on the team, off his shoulders,"
"And when he arrived here I felt him a bit mentally tired, a bit still worrying about the situation. Marcos was here the whole pre-season, he did every single training session and he took this opportunity and was so, so great, with such huge quality and attitude,"
"So Marcos was crucial for us from the first day in training, and then he delivered in Chilly’s position. And these are our two specialists for the same position, so this is a tough competition for both of them,"
"But he’s in the race now, the situation has changed for him. He’s in a good mental shape and attitude, and a good shape on the pitch. So he can play any minutes. Because you feel he did everything to push the team, you feel part of the team but you don’t feel it really if you don’t sweat it out sometimes on the pitch and you never wear the shirt,"
"And if you’re never really involved, it is a strange feeling. Then of course it was necessary to keep training and training for five weeks, continuously, and then he had a break, a personal break,"
"We had talks with Chilly about the situation. There are no further worries for Chilly He has to be patient and keep on training,"
Chilwell will be hoping for some action in the Champions League when Chelsea host Russian side Zenit St. Petersburg on Tuesday night.
