Ole Gunnar Solskjaer has overseen a "culture shift" regarding transfers at Manchester United, according to Phil Neville.
United spent the most of any Premier League club over the summer when bringing in Harry Maguire (£80m), Aaron Wan-Bissaka (£50m) and Daniel James (£15m).
Maguire produced a man-of-the-match performance in United's 4-0 win against Chelsea on Sunday, with James also on target in their Premier League opener.
Solskjaer saluted his new recruits after their seamless adaptation to life at Old Trafford, and Neville believes his former United team-mate has built a squad which will "fight right until the end".
"They were more together, definitely," Neville said. "It is early days but it was a fantastic game of football. In pre-season I've seen a real together, unified team playing a certain way and system. There's been a shift in culture with the players brought in too.
"The best moment on Sunday was when James scored that goal and the emotion in his face about what it meant to him.
"Playing for Manchester United should mean something to you, and the signings Ole has made and the likes of (Mason) Greenwood, (Angel) Gomes and (Tahith) Chong coming into the squad means the bare minimum we'll see is a Man United team which will fight right until the end."
Neville also singled out praise for Scott McTominay, hailing the midfielder's dedication as he battles for a place in United's starting XI.
"He's an impressive young man," Neville added. "There are probably more skilful players, players with better reputations than McTominay, but if you're talking about character and resilience, that lad's gone through it all to get to where he wants to be. That's through sheer hard work, dedication and training and doing extra.
"It's no coincidence Jose Mourinho picked him in the biggest games against Chelsea and PSG, and Ole's doing the same now.
"There's nothing better than a level-headed young lad absolutely working his socks off. The fundamental basis of any successful person is hard work, and Scott McTominay is doing that in abundance."
