​Manchester City boss Manuel Pellegrini did not hold bakc after his side went down 2-1 to Everton at Goodison Park in the first leg of the Capital One Cup semi final, turning to the referee as to why his side will need to turn the deficit around if they want to make the final.

Speaking to the Citizens' ​official website after the game, the Chilean said, "The first goal was offside. He [Lukaku] was in front of Willy Caballero and it is unbelievable that the linesman did not see. 

"If you aggregate the clear penalty that we should have had for Jesus Navas - both of these are clear observations that can change the score. It was a foul, it was clear – he took the legs of Jesus - it was a clear penalty. But the referee didn't whistle for both actions. I give my opinion because they were so clear.

"We didn’t deserve to lose in the first half – they scored a goal that was absolutely offside and then we were denied a clear penalty. It was important to draw level at the moment we did. We were playing better - but Lukaku is a dangerous player.

"We have only played 90 minutes - it is important not to concede another goal. We can progress if we play the way we normally play at home."

Pellegrini went on to discuss his selection options over the next few games, after Eliaquim Mangala was taken off at half time, "Mangala has a problem in his hamstring,. Of course it is a problem. We have just two centre halves, Otamendi and Demichelis and we have to play six or seven games more in January. It is a lot of games."

He also told ​ESPN about his determination to stick with second choice stopper Willy Caballero for cup games, "Willy is playing the Capital One Cup. He will continue in the FA Cup also. I think he played very well."
