Chelsea boss Thomas Tuchel admits N'Golo Kante is a big doubt for their Champions League quarterfinal first-leg clash with Porto.
The French midfielder returned to Chelsea early from international duty after picking up a small hamstring injury and Tuchel has confirmed that instead of training with the rest of the squad today, Kante undertook some individual work ahead of Saturday's meeting with West Brom.
The manager said, "With N'Golo, we will have to be patient. Will he miss the Porto game? Yes, probably. He is doing individual training and tomorrow's game comes too soon for him and so he can't be with the squad.
"After tomorrow's game, we have just three days to prepare [for Porto]. He has a muscle injury, as we communicated with the national team, so my realistic approach is to think further ahead about Porto, maybe the second game against Porto he could be available for."
