Barry has been linked with several managerial positions, most recently the vacant job at Huddersfield Town. But the Blues have turned down approaches from other clubs to hire him for their own backroom team, as Potter sees him as a valued member of the setup due to his set-piece expertise and man-management skills.

The Englishman, 36, has previously worked with the Republic of Ireland and currently has a part-time role with the Portugal national team. There is no indication yet as to whether Barry would push to join Tuchel, but he has previously revealed his admiration for the German boss and that could be crucial to convincing him to leave.

"From Thomas to Arno, Benni [Weber] and Jogi [Zsolt Low], these are top people," Barry told the club's official website in July 2022. "The way they’ve been with me and the way they’ve brought me into the staff, I couldn’t be more thankful.

"The level of work that they produce, for a young coach like me to be around it, to help and share my ideas inside a circle like that, is simply first-class."
