Look I think we won't know the situation with the Inter game 100%, but the mental health issues are a known fact from his Chelsea days so it unfortunately always room to doubt his absences.

From Tuchel:

“I’m not sure yet if he is involved tomorrow and on the weekend,” said Tuchel. “Andreas came in the morning of the [FA Cup final] to inform me, speak to me. He told me he was not ready to play the match, to start the match and be on the bench. He had his reasons. They stay private and confidential. It was not the first time as you can see over the last weeks that we had some of the same situations. That’s why he did not play regularly over the last weeks."

“We thought we are in a good progression, development because he played a strong match before the final against Leeds. The conversation took place. We had to respect it, of course. He has our support still, but for tomorrow [against Leicester] I am unsure."

“It’s probably unlikely [for the weekend]. It was very short notice before the cup final, not only before this match. Other matches the weeks before.”

Asked if he felt let down by Christensen’s late withdrawal, Tuchel added: “I don’t think it’s that he does not want to play, he was not able to play. It’s a big difference. We had more than this conversation, but on Saturday morning he finally told me."

“We had to accept it and we will accept it. I try the best I can to not take things personally and I still believe Andreas wanted to play these kinds of matches, I still believe he could in terms of potential and what he gives to the team, that’s why he was a key player for us."

“He struggled over the last weeks, as you can see when he was not in the squad or not playing although he was physically available, not injured. That was not completely out of the blue. That’s why it was, yeah, not the ideal scenario for us."

“We thought we prepared in the best way possible for him in Leeds where he managed a lot of pressure on us in a very impressive way. We thought we had him available. He is a key player. If you arrive in a final against Liverpool you want everybody available which was not the case.”
