Manchester United manager Erik ten Hag admits he enjoys watching Manchester City play.
The Citizens are one of the most impressive teams in Europe at present, as they are on course for the treble.
Having already won the Premier League, City take on United in the FA Cup final this weekend, and then play Internazionale in the Champions League final a week later.
Speaking on Football Focus on BBC One, Ten Hag stated: "I think that the rivalry and logical and normal on both sides and you have to respect each other.
"Of course, on Saturday we will fight each other. It's a big game an FA Cup final - huge. Any game with Manchester United and Manchester City is huge, but when it's a final it's special, of course."
Ten Hag added: "Every game you learn lessons. It's really enjoyable to watch Manchester City, but we have to stop them and we have to make it our game. We have proved we can beat them, but we have to play to our level. If we have belief, anything is possible."
"As a child you dream... We want to win that cup and we know it's going to be tough because you play - probably - against the best team in the world at this moment in time."
