Manchester City boss Manuel Pellegrini refused to seek excuses for defeat at West Ham United.
Pellegrini could see his side fall eight points behind leaders Chelsea if the Blues win at Old Trafford on Sunday.
The Chilean refuted claims a Champions League hangover, after their trip to draw 2-2 against CSKA Moscow, cost his side a victory and accepted it was the profligacy of his team which saw them lose.
"I don't think that the team felt what happened on Tuesday in Russia," Pellegrini said.
"Of course I'm very disappointed about the score as I don't think we deserved to lose the game.
"We had two or three clear chances we couldn't score. West Ham played well in the first half but we improved a lot in the second, but if you don't score that goal you can't win.
"I'm always concerned about my team, what the other teams do is not my concern - we will see what Chelsea will do but we have 87 more points to fight for."
