But even if Thiago is available, Tuchel still faces a decision over whether to Andreas Christensen out of the team after his outstanding performances in recent weeks.
The Chelsea manager said: “Andreas stepped in in the middle of the first half against Tottenham, which was a really tough thing to do, and from the first minute, he’s been absolutely impressive.
“He’s brave, strong in individual challenges, brave and intelligent in the build-up, and plays with a lot of confidence.
“I am absolutely happy with his performances and how he’s stepped up. He’s been a big part of our performances.”
