But Tuchel confirmed earlier this week that he plans to keep the 22-year-old at the club.
He said: “Well, I think he did a fantastic pre-season with us, he’s a very good player and even more important a top character.
“He has both feet on the ground, he took his chance very impressively, he played very good matches in pre-season, he performed for 120 minutes against Villareal and then another strong 90 minutes against Crystal Palace.
“So now I think it’s very logical that he stays with us, and he’s looking for his chance here.
“We let some players go but Trevoh is a guy we absolutely want to keep, and this is the status for him.”
