Ralf Rangnick may only be taking temporary charge at Manchester United until the end of the season, but Diogo Dalot has revealed the "demanding" changes that the German has already made.
Dalot has seen his game significantly increase under Rangnick, as the interim boss has prioritised both him and Alex Telles on a more regular basis, as opposed to the English pairing of Luke Shaw and Aaron Wan-Bissaka.
United grabbed three vital points on Saturday as their 3-2 win over Tottenham kept their top four hopes alive in the Premier League, and they face a crucial Champions League tie against Atletico Madrid on Tuesday.
And ahead of their second leg against the Spanish champions, Dalot has lifted the lid on Rangnick's changes at United.
HAVE YOUR SAY: Who should be Manchester United's next manager? Comment below.
United were initially improved under former boss Ole Gunnar Solskjaer, but it all went wrong for the Norwegian, and Rangnick was brought in to handle proceedings until the end of the season.
The Red Devils have opted for a high-intensity approach, and Rangnick's side have become difficult to beat, with only Manchester City and Wolves denting their record since the German was appointed.
Dalot opened up about Rangnick's changes in an interview with UEFA, as he said: "Ralf talks a lot about anticipation and being proactive, and that's one of the things that I've been trying to work on the most because sometimes being at the right place at the right time can stop you making mistakes.
"We have a demanding type of game, a demanding style of play; you want to press really high, but you also want to be careful with balance at the back.
"Then when you have the ball, you have to play forward, you have to be intense, you have to help the team in the last third as a full-back.
"However, you also have to be ready to defend as well. It's demanding, but we're at a club where everything is demanding. Everything is the highest level, highly competitive."
United face Atletico in the second leg of their Champions League knockout tie on Tuesday, with the score currently tied at 1-1 on aggregate, and Dalot also thinks that their opponents share this intense, dogged mindset that Rangnick has implemented.
Dalot added: When I think of Atletico, obviously I don't know [them] from the inside, but what I can see from the outside is their values, the way they express themselves, their desire.
"We have a word in Portuguese to describe this desire to win every single ball, hunting down everyone, defending... being there for 90 minutes, fighting for each other and trying to win every single ball as if it was the last.
"We need to be ready for everything, because they're a fantastic team, not only in La Liga, but also in the Champions League.
"They've been having a fantastic season, and they've shown what they can do over the last couple of years. I'm sure it's going to be a very good game to watch, and hopefully we can go through."
