The England international insists Roberto Mancini's side will go into the Manchester derby "with a little bit more confidence" following Sergio Aguero's late winning goal
Manchester City midfielder Gareth Barry has revealed how Sergio Aguero's last-minute winner against Villarreal on Tuesday night has given the side a huge confidence lift ahead of the Manchester derby.
The vital Champions League clash was heading for a 1-1 draw before the Argentine striker scored deep into stoppage time to give the Blues a crucial win.
And the former Aston Villa player admitted that a last-gasp winning goal should give the squad much needed momentum and confidence ahead of this weekend’s meeting with Manchester United.
He told reporters: “A last-minute goal can lift everyone - it is a massive confidence booster.
“We will just go into Sunday's game, knowing it is a massive one, with a little bit more confidence.
“But it is not a place you can go and relax - we have got to go and play our best game of the season to get something out of it.
“We respect Manchester United and hopefully it will be a good game.”
England international Barry hopes the 2-1 home win over the Spanish side on Tuesday night can propel them to the knockout phase of the competition with three games remaining in the group.
“We knew we really had to get the three points,” the midfielder continued.
“We fought right to the end and you can't really beat a last-minute winner, so it was a good feeling in the dressing room.
“It was similar to when we played Napoli at home. They are good in possession and counter attack quickly.
“We are still learning in the Champions League and it is such a tough group.
“This has lifted everyone. We knew three points were vital to go on and qualify from the group but this is just the start.
“It is a massive lift but we have just got to build on it.”
Barry was left out of the City starting line-up but was brought on 40 minutes into the match for Adam Johnson, who looked understandably disappointed to be withdrawn so early.
Barry, 30, was surprised at his early appearance from the bench but City’s first goal soon after he came on helped justify manager Roberto Mancini’s decision.
He added: “It was a surprise but I was warming up for a while in the first half so I knew the manager was maybe thinking of making a change.
“I went on and it was important we scored just before half-time.”
