Manchester United fullback Luke Shaw says manager Erik ten Hag is relentless in his demands every day.
Shaw was speaking after their FA Cup semifinal penalty shootout win against Brighton on Sunday.
He said, "I think us, as players, we can never take anything for granted.
"Every day with this manager you have to be 100 per cent at it in training, around the place, because he sets high standards. If you don't meet them, you don't play no matter what the circumstances are - whether there are injuries, suspensions, it does not matter.
"So, for me, I don't take it for granted. Still, the back end of the season is the most important, that's when you win stuff, and we want to win this trophy so we have to give it everything.
“Obviously it's not easy (playing at centre-back). If it was in a three, it's a bit different. But when it's two, it's a lot different, to be honest.
"But whenever I play there, I really enjoy it and obviously we had a couple days (to prepare). The manager spoke to me about it and Victor (Lindelof) of course because against a team like this they're very tricky, a lot of tactical (information). Sometimes I had to stay in the middle of the pitch to follow them.
"So it's something new but I love playing there, I love playing football. To get the win today was the most important thing."
The England defender concedes Ten Hag was demanding better after last week's Europa League elimination by Sevilla.
"He said that's a team out there today and he wasn't sure who or what was there on Thursday night. But obviously that wasn't acceptable.
"Today, I think it doesn't put things right but it puts us in a good place to finish the season well because Champions League is a must for us and a Manchester derby now in the FA Cup final is an amazing game to be involved in.
"At the start of this week, it was the biggest week of the season. There was no doubt about it. A massive game in the Europa League and then of course, this. It will have defined our season.
"I think if we get knocked out both of them, then you're right about the season (looking different). But I think today was a massive game, a massive opportunity to get into another final against a very good side and one I think everyone's going to look forward to being involved in."
