Manchester United produced an impressive comeback to beat Newcastle 4-1 at Old Trafford on Saturday evening.Goals from Anthony Martial, Chris Smalling, Paul Pogba and Romelu Lukaku helped Jose Mourinho's side bounce back from the recent 1-0 defeat at the hands of Chelsea.Pogba, 24, started the game after over two months on the sidelines with a hamstring injury.The talented French midfielder was sorely missed - whilst Manchester City extended their lead at the top of table to eight points - and won the Man of the Match award on his return to first team football.Swedish striker Zlatan Ibrahimovic also made his return against Newcastle - seven months after suffering a serious knee ligament injury.Unsurprisingly, the Man United players were in high spirits in the dressing room after the full-time whistle.

The French forward has been vying for a place in the starting XI with Marcus Rashford but Mourinho selected them both together against Newcastle.

Rashford and Martial were a constant threat to the Newcastle defence and Manchester United fans certainly enjoyed watching them both together.

Martial, who has been in electric form so far this season, now has a goal or assist every 67 minutes.

The 21-year-old French international posted a hilarious, if a little bizarre, video on his Instagram story.

Pogba, Lukaku and Lingard serenade Martial

There was plenty of criticism in the English media after the Red Devils splashed out a club record fee on a teenage Frenchman from Monaco.

Manchester United fans have taken great pleasure in Martial proving journalists wrong and created the following song during his incredible debut season in England:

'Tony Martial came from France,

English press said he had no chance,

£50m down the drain,

Tony Martial scores again.'

The chant was ringing around Old Trafford on Saturday and Martial filmed Lingard, Pogba and Lukaku singing and dancing to the song in the Manchester United dressing room after the full time whistle.

United fans react

Some fans were wondering exactly what Roy Keane would make of this kind of behaviour, following a routine win over a newly-promoted side.

The reaction on Twitter was definitely mixed.
