Jadon Sancho hailed the early work of Erik ten Hag at Manchester United, saying the Dutchman has made the same players feel like a "whole different team".
Ten Hag has a sizeable rebuilding task at Old Trafford following the unsuccessful interim spell of Ralf Rangnick, whose mid-season appointment to replace Ole Gunnar Solskjaer failed last campaign.
United finished sixth in the 2021-22 Premier League campaign after recording their lowest points tally, while failing to end a league campaign with a positive goal difference for the first time since the 1989-90 season.
The former Ajax coach has brought in Tyrell Malacia and Christian Eriksen, while striking an agreement for Lisandro Martinez and reportedly holding negotiations with Barcelona for Frenkie de Jong.
United have also impressed in their pre-season friendlies, defeating Liverpool, Melbourne Victory and Crystal Palace, and Sancho was quick to credit Ten Hag's early influence.
"He's told all the boys that every friendly is a must-win game," the winger said to United's official website.
"I can already tell from his mindset that he wants us to do well and, when the players hear that from a manager, you all take that in and we all want to give our best, especially out on the pitch.
"That's been a real confidence boost. We've been having lots of meetings with the manager and understanding how he wants us to play and there's definitely been a big sign of everyone taking that on board and us producing what he wants to happen.
"This pre-season, we have the same players but it just looks like a whole different team and I do think that's something we're working on and I feel like we're getting better.
"The manager is big on team-bonding and having fun together and doing things like team dinners and things like that. So, yeah, it's helping.
"You can see in the games, as I said before, with how we're playing and there being a lot more structure and opportunities to score, and we're keeping the ball more too and being effective [with it]."

Sancho arrived from Borussia Dortmund last season as the only player from Europe's top five leagues to have scored 10 goals or more and at least 15 assists across all competitions in each of the previous three seasons.
But the England international struggled in his debut season in Manchester, scoring just three times in 29 Premier League appearances and he is keen to make amends in the upcoming term.
"Last year wasn't great and I feel like everyone has something to prove for this upcoming season," he added.
"It's my second year now, settling into the team, knowing how players play and I'm excited for the upcoming season, with a new manager and how he wants us to play, and I think it will be good for myself.
"We don't want to put performances in like we did last year and upset the fans. Some fans travelled for a long time to get to the stadium and watch us not perform.
"I'm sure, this year, everyone is going to make up for that and make sure every game we play we put 100 per cent in and make sure the fans are smiling at the end of the game."
