Gareth Barry believes that Manchester City’s last minute goal against Villarreal this week has shown the side that they have what it takes to topple Manchester United this weekend and win the derby.
Sergio Aguero scored in the 93rd minute to take City to their first Champions League win, and push the side to within a point of second placed Napoli in the Group A table.
And Barry believes that the goal will help City, who have notoriously lost recent derbies to United thanks to last minute goals, stand-up to their rivals and steal a win at Old Trafford.
"A last-minute goal can lift everyone - it is a massive confidence booster," Barry said.
"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."
The win in the Champions League was particularly important for City to stay fighting for a place in the last 16, and Barry believes that while the side are still finding their feet on the European stage, they are getting better.
"We knew we really had to get the three points," he explained. "We fought right to the end and you can't really beat a last-minute winner.
"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."
