Manchester United must have a good team, attitude, and cooperation if they are to defeat Manchester City at the weekend.
The Red Devils are on an impressive run of wins in all competitions, managing eight straight successes.
However, they take on reigning Premier League champion and neighbors City on Saturday.
“I think we can compete with every team but obviously Manchester City, when they're at their best, they are hard opponents for everyone, but we have to play our best and then we have a chance," Ten Hag told talkSPORT.
"If we do it, [play] like in City [in the 6-3 defeat], then you don't have a chance. So it's up to us to have a good team, the right co-operation, the right attitude on the pitch, especially if you talk about attitude. So a winning attitude.
"That is what we need on Saturday. It's by standards [improved results]. By every day, living along high standards. It's by the team, building a team. Nobody is bigger than the team, everybody has to contribute to the team.
"That's not about 11 players but the whole squad. It's the team around the team. All the staff – the medical staff, the performance staff, the coaches, the analysts. Everyone has one aim and they're contributing to that and working hard for that with togetherness. When we keep this going, we can achieve a lot."
