Manchester United have been in good spirits in recent weeks.Prior to Sunday's match against Watford, United had recorded four wins from their last five games, which included victories over both Tottenham Hotspur and Manchester City.But United's unbeaten streak came to an end as they were beaten 2-0 by Watford at Vicarage Road.After a goalless first half, David de Gea's disastrous mistake shortly after the break gave Watford a shock 1-0 lead.And Troy Deeney would convert from the penalty spot just minutes later to double his side's lead.

United huffed and puffed to try and get back in the game, with Ole Gunnar Solskjaer sending on Paul Pogba to try and salvage a result.

But it would be to no avail as United slumped to a 2-0 defeat.

One man who was upset with the result is Sky Sports pundit, Gary Neville.

And, in some brilliant footage, Sky Sports actually managed to capture Neville's reaction to De Gea's awful mistake.

Watch De Gea's mistake below:

Neville and Geoff Shreeves were interviewing Tottenham manager Jose Mourinho when De Gea made the mistake.

The former United defender let his emotions get the better of him and so stunned that he had to interrupt the interview that was taking place.

Watch Neville's reaction to De Gea's mistake below:

"Look at that!" He can be heard saying in disbelief. "Oh my God!"

Neville was every United fan went that goal went in.

While Neville looked absolutely gutted, Mourinho simply looked on without giving away his emotions.

Maybe, deep inside, he was happy as he watched his former side succumb to another embarrassing defeat.
