He was let go in May 2016 to make way for Jose Mourinho following a season hallmarked by soporific football and a fifth placed finish in the Premier League.
Speaking on Sky Sports, Neville made note of how Van Gaal’s time at Man United continues to impact on the side’s performances.
“If you’d have said to me six years ago that Manchester United were the title winners and then would spend £700m in the next few years, I would have said that they would have won multiple titles.
“So Jose Mourinho has had to get out of the club seven, eight, nine, 10 players, and then get them in. He’s only been here two years, he’s not been here 15 years. So for me there is still more investment to do to make up for the mistakes in those first three or four seasons.
“I actually like the signings Jose Mourinho has made, they’re more along the lines of the players I’d like to see at this football club.”
United had to rebuild after Sir Alex Ferguson‘s retirement. They then had to rebuild – if only psychologically – again after David Moyes. The biggest rebuilding job, however, came after Van Gaal, who unlike his two predecessors heavily invested in the squad.
The likes of Angel Di Maria, Daley Blind, Memphis Depay, Bastian Schweinsteiger, Matteo Darmian, Morgan Schneiderlin, Luke Shaw and Marcos Rojo were all brought in to serve as the backbone to this United team. All of them have either left the club, are about to leave, or lie on the fringes of the current side.
Mourinho may have been United boss since June 2016 but he will not yet feel like this is entirely his team, especially after a disappointingly fallow transfer window this summer.
