Berge, the United midfielder, made the claim despite his club’s difficult start to the new season, which has seen them lose five of its last six games.
Despite spending more than £1bn in the transfer market over the past decade, collecting a scintillating array of talent including Kevin de Bruyne and Raheem Sterling, City have also been in disappointing form of late; winning only two of their first five Premier League outings so far this term.
Speaking ahead of today’s lunchtime kick-off, Berge said: “I go into every game thinking we can win, thinking that we can beat our opponents and attack the players that we’re facing.
“They (City) have got world class players in every position. But we don’t want to just defend. I believe we can go at them as well. We want to play to our strengths, which are fighting together and being aggressive when we can, just like we did last time out.”
Capped 23 times by Norway, Berge was referring to United’s display against Liverpool seven days ago, which saw him fire them in front from the penalty spot before goals from Roberto Firmino and Diogo Jota saw the reigning champions avoid a shock defeat.
Although Wilder insisted that performance shows United’s morale is still high - “If we play like that all the time, we’ll definitely be okay” - he acknowledged people will still be expecting City to “roll us over” given the names at their disposal.
Berge admitted United will enter the match as underdogs, but confident they can rise to the challenge.
“City will be coming in thinking about their own strengths more than out strengths,” he said. “I understand why, when you look at the players they’ve got. But at the same time, I think that always gives you a chance because, when they come at us, which they will, then we know we have the opportunity to attack them back.”
