Kepa Arrizabalaga was at goal against Dinamo Zagreb.Ahead of the clash against the Croatian side, Tuchel had said about Mendy's injury:"He was in a lot of pain, and we have to see. It's too early to comment on that. I think at the moment he is a bit unlucky in what he is doing. In training, he is fantastic, and he is, in general, a very calm and self-reflective guy who is aware that he lacks a little bit of luck at the moment."It's unclear when Mendy will return to action.Pierre-Emerick AubameyangAubameyang is likely to feature against Red Bull Salzburg, like he did against Dinamo Zagreb as well. The Gabonese striker suffered a jaw injury during a robbery at his house in Barcelona last month.He moved to Chelsea from Barcelona earlier this summer and made his Blues debut against Dinamo, playing 59 minutes with a mask.N'Golo KanteKante suffered a hamstring injury during the Blues' 2-2 draw against domestic rivals Tottenham Hotspur in Gameweek 2 of the Premier League.Before their win over West Ham, Tuchel had suggested that the Frenchman might be out for a few weeks, saying:"With N'Golo, we are talking about weeks.
