Thought the players looked motivated and fully trying against Leipzig, it wasn't a lack of effort that cost us. Them taking fairly low probability efforts while we were toothless cost us.
Mourinho rightly praised their attitude after the game.
The simple fact is that with Kane, Son, Bergwijn, Sissoko, Sanchez, Davies all injured, Ndombele lacking fitness, Sessegnon just returning from injury and several of our players having played an awful lot of football recently there was a significant gap in quality between us and Leipzig.
If the players will respond well to what Mourinho is saying for the rest of the season remains to be seen. I think his comments can be seen as downplaying expectations and thus protecting our players. I don't think that's wrong in itself in the situation we're in.
