The Red Devils looked to be in command of the Premier League clash thanks to Ashley Young’s two goals inside six first-half minutes.
France international Anthony Martial made it 3-0 in the 32nd minute to seemingly secure three points from Jose Mourinho’s men.
However, Argentina international Marcos Rojo conceded a penalty in the 77th minute which allowed Watford captain Troy Deeney to reduce the deficit.
Abdoulaye Doucore made it 3-2 to cause some panic in the Manchester United side having led the Premier League clash comfortably.
But Manchester United midfielder Lingard ran half the pitch and evaded three challenges before he placed a finish past the Watford goalkeeper.
Ex-Red Devils defender Neville was clearly thrilled with Lingard’s goal to allow Manchester United fans to breathe a sigh of relief.
Neville retweeted Manchester United’s post celebrating Lingard’s solo effort and posted a series of heart emojis.
Neville wrote: “❤️😂❤️😂❤️😂❤️”
Manchester United have won their last three Premier League games thanks to victories over Newcastle United, Brighton and Hove Albion and Watford.
The Red Devils finished in sixth place in the Premier League last term but are five points adrift of leaders Manchester City.
