The Red Devils have struggled to produce consistent form this term in what is Jose Mourinho’s second season in charge at Old Trafford.
Manchester United had been hoping to challenge for the Premier League title this season, but the Red Devils were unable to prevent Manchester City from dominating the top flight and winning the title.
Mourinho’s men suffered a shock 1-0 loss to West Bromwich Albion at Old Trafford on Sunday as they handed the title to Manchester City.
And former Red Devils defender Neville feels that Manchester United need to make a number of new signings this summer and also let a host of players go.
Speaking on Sky Sports’ Monday Night Football, Neville said: “I didn’t see it [the defeat by West Brom] coming, it was a dismal, weak day for United. They started the season trying to rid themselves of these performances.
“Mourinho referred to attitude and consistency, he needs to identify the ones causing those problems and they need to go. I think there will be three or four players leaving and the same number coming in.
“He’s got to make that gap up and it’s going to be tough. Consistency is about mentality and the players fell well below that considering the last couple of weeks.”
Manchester United are still aiming to try and end the season with a trophy, and they will take on Tottenham Hotspur in the FA Cup semi-finals at Wembley on Saturday afternoon.
The Red Devils finished in sixth place in the Premier League last season, but they won both the Europa League and League Cup under Mourinho.
