London: Manchester City manager Manuel Pellegrini has admitted he is “worried” about his side’s form after they were knocked out of the League Cup by Newcastle United.

The holders fell to a 2-0 defeat at the Etihad Stadium on Wednesday and have now gone three games without a win ahead of Sunday’s derby at home to Manchester United in the Premier League. They also lost 2-1 at West Ham in the Premier League on Saturday and were held 2-2 at CSKA Moscow in the Champions League last week.

To compound matters, influential midfielder David Silva was forced off by an early knee injury, and Pellegrini conceded after the game that he has problems on his hands.

“Of course we must be worried — we didn’t win the three games we played this week,” said the Chilean, whose team have also made a slow start in the Champions League.

“We must be worried about that, but we must find a solution and we must address it. We will see with the players which is the way to try and recover that confidence because it’s not normal to see this team playing the way we are now.”

He added: “My feeling is that we are not playing well. We are in a difficult moment with a lack of trust.

“We are conceding too [many] easy goals and we are not scoring the chances we have to score. That’s the feeling at this moment.

“It’s a lack of confidence that we must address as soon as possible because we need to continue to be involved in the other competitions.”
