Despite Manchester United’s largely poor form under Ten Hag, Neville believes he will at least partly be remembered for lifting two trophies and giving the fans a ‘special’ win over Man City at Wembley.
But Neville also says Ten Hag will be remembered for ‘overseeing two of the worst transfers Manchester United have ever made’ in Antony and Casemiro.
‘[Erik ten Hag’s] legacy will definitely be winning those two trophies but particularly the Manchester derby in the FA Cup final,’ Neville said on The Overlap US.
‘That was a special day for every Man United fan that won’t be forgotten. It was a really, really great day and that won’t go away.
‘I remember how bad it was when David Moyes got sacked and the problem is over the past ten years we’ve had another group of managers, including Erik ten Hag, who have not done much better.
‘I just hope in five year’s time we aren’t looking back and still thinking that. It’s all about the club getting it [the next appointment] right.
‘The performances have been really poor this season, the results have been shocking, the league position is terrible. So he can’t complain.
‘His legacy is definitely winning two trophies in two seasons through a very difficult point.
‘The recruitment to be fair has been appalling for ten years and he’s been a victim of that himself.
‘I think he oversaw two of the worst transfers Manchester United will ever have made in the signings of Casemiro and Antony.
‘They were signed for £140-150m in a panic after the Brentford and Brighton losses. I hope I’m wrong, I hope Casemiro can do a great job for the club for four or five years and I hope Antony comes good.
‘But those signings are why United have had to go back into the market and sign [Manuel] Ugarte and other players.
‘That was the ultimate in poor management from those above Erik ten Hag. That should have been one big fat no when those two players became available for those prices and those salaries.’
‘Erik ten Hag brought me back to Manchester United in the summer and, while I have only been part of the coaching staff here for a few months, I will always be grateful to him for giving me the opportunity, and I am saddened to see him leave.
‘Even on an interim basis, it is a great honour to manage the club I love for however long I am asked to do so. I can promise that I will continue to give my all, in whatever capacity, to try to turn around our fortunes.
‘Despite our results, I am loving being back at Old Trafford and working with the team and staff every day.
‘We’ve seen the squad’s potential at times this season, but clearly not often enough. Now is the time for everyone at the club to work together, give everything and turn this season around while we have time.
‘From my experiences as both a player and a coach here, I can say for sure that when players, staff and supporters pull together, Manchester United can be unstoppable.’
