Manchester United manager Erik ten Hag says winning the FA Cup final should be enough motivation for players today.
United can also stop Manchester City from winning the Treble.
But Ten Hag says: “I know what is the thinking from the fans but what we want is to restore Manchester United by winning trophies so we have an opportunity to win a trophy and we don’t want to be distracted by anything.
“If it is important for the fans it is important for us so we will give everything to win the Cup. But it is not about stopping them.
“Because it is not necessary. It will not give more motivation for the team because for their motivation is already enough – it can’t be more.
“They want to win a Cup and they have an opportunity. They want to set a crown of the season so what do you need more? What is more motivation?”
This season United lost 6-3 at City before winning 2-1 in January.
Ten Hag added: “You learn from that defeat but you learn from the win as well but I can’t say afterwards that I learn something from that game so we won the second game – I don’t think so.
“What was the difference between those results? The belief. In the Etihad we didn’t show belief. In Old Trafford we were determined to win this game from the first moment on. It is up to us that we show the same belief.”
