Chelsea boss Thomas Tuchel admits he'll make major changes for their Champions League clash at Zenit.

Chelsea are already through to the knockout stage of the competition.

"It's a good chance to but the decisions have not been made yet because we've just had training and we had a bit of an acute overload also due to injuries and the schedule but the schedule is the schedule, the players can handle this," said Tuchel.

"Due to injuries in some positions, like central midfield, we struggle, but the game tomorrow is not a problem in terms of being overloaded.

"We had one day off, two good training sessions, and the guys look fresh. They are ready for tomorrow. We can let anybody play from the 17 players plus goalkeepers, but the problem is the next match on Saturday because we will lose time to sleep. We arrive in the very early morning of Thursday.

"So, it's a long story and short message. There's a huge chance that we rest some players and, more importantly, we'll give some players who need the load, minutes and rhythm."
