Strachan told OLBG: "Manchester United have an issue in their FA Cup against Liverpool if Jurgen Klopp makes changes because they won't get praise for beating a lesser team, but if they lose to them it will be a tragedy.
"The pressure can be a real problem with the mindset of Manchester United players, so you have to think about the mental side when they play Liverpool.
"Some players have come out and said that they shouldn't be criticised if they are trying their best but if you're getting heaps of money then it's part of the deal. If you're at Manchester United then you have to deal with it.
If you don't like it then you should go and play for a lesser club, whether it was 40 years ago or now it's magnificent to play for Manchester United and the fact is you have to deal with stress."
