Tuchel has previously claimed fault for the Moroccan’s lack of game time at Chelsea and admitted to some strenuous selection headaches.
Speaking in February, the Germain said: “It is my fault, it is my decision. For Hakim and some other players here are hard decisions to make, it is a good thing because it means we have quality.
“There are some decisions for other players that means Hakim suffers at the moment, I can understand so it is my responsibility in this case that he cannot show more.
“When I look at the rhythm and schedule for the next days I am sure we will need all of our players.”
Ziyech had started just 11 matches under Tuchel in his time at Stamford Bridge so far – netting just one Premier League goal during that period.
In fact, the 28-year-old was an unused substitute for the UEFA Champions League final win vs Manchester City.
After a frustrating first season in West London following a big-money move from Ajax, last summer, Ziyech has now been linked with a move away.
Ziyech scored just six goals and provided four assists during his debut campaign in West London. He still has four years left to run on his Chelsea contract.
