Seydou Doumbia scored what proved to be a 34th-minute winner in the Group E clash after Yaya Toure had cancelled out the CSKA striker’s early opener at Etihad Stadium.
The performance of the team depends on individual performances and, I repeat, it’s difficult to understand why we are at this level
Fernandinho and Toure were sent off in the second half and will miss the club’s next game against Bayern Munich, which the Citizens must win before beating Roma to have a chance of progressing to the knockout stage.
“It’s very difficult to understand why we played so badly,” Pellegrini told Sky Sports.
“From the beginning we were so nervous. We lost so many passes and we gave them the two goals. Really, we didn’t play.
“It’s difficult to know why you have so low a performance. In the way we tried to play we have not changed anything we did in any other games. I realise it’s a very difficult and strange moment to understand why it happened.
“I don’t think it’s just this competition. I think in the last two weeks we are not playing bad, but we are not playing the way we normally do.
“I don’t understand why, but we must find the reason to arrange the solution.
“The performance of the team depends on individual performances and, I repeat, it’s difficult to understand why we are at this level.”
