Man City boss Pep Guardiola says his side are in 'big trouble' ahead of Liverpool clash

Guardiola’s side battled an intimidating atmosphere and a fired-up home side at the Wanda Metropolitano to edge a tense quarter-final courtesy of last week’s equally-draining 1-0 first-leg win.

Atletico finished with 10 men as Felipe – who escaped a booking for a terrible challenge on Phil Foden in the first half – was sent off as home frustrations boiled over in the closing stages.

City have injury concerns ahead of Saturday's FA Cup semi-final against Liverpool and Guardiola painted a gloomy picture on a night when Kevin De Bruyne was among those picking up a knock.

"We are in big trouble, so we can't forget we played three days ago, travelled, come here, have a lot of injuries now and I don't know what will happen in the next weeks," stated the City manager.

"Today we celebrate because it is the third time in Manchester City's history we are in the Champions League semi-finals.

"This was the champion of Spain and they played with energy and in second half were better than us and we were lucky we didn't concede. In the first half we had chances, overall we are in the semi-finals - it is well deserved.

"The opponent is so tough, all the teams in Champions League come here and suffer so it is important we go through.

"We cannot play all the time and score four or five goals, we are human beings - we come from a difficult game against Liverpool."

City midfielder Jack Grealish was involved in a battle with Atletico Madrid players in the tunnel after the game and City defender John Stones suggested they knew what was coming from their rivals.

"We know that they sometimes try and make things happen like that and we dealt with it really well," he stated. "It is not nice to talk about and I don't want to dwell on it because over the two legs we played incredible against such an experienced side in what they do, we kept our tempers and it is easy to get drawn into stuff like that.

"We knew it was not an easy place to come, it is a hostile environment, it was a difficult night all round and how we defended and controlled ourselves over the two legs was incredible."

Rio Ferdinand pointed an accusing finger at Atletico Madrid's players after unsavoury scenes at the end to a tense Champions League game against Manchester City.

"Distasteful behaviour from the Atletico players, they should be embarrassed with some of the antics they have gone on with," said 2008 Champions League winner Ferdinand on BT Sport. "Either Jack (Grealish) has said something that we haven't seen or they just don't like the look of him. It is weird.

"You have to say, talking about football, well done to Atletico Madrid as they made Manchester City play in a way we haven't seen for a long time, took them out of their rhythm and their stride. But some of the stuff towards the end was not what you want to see on a football pitch."
