Roy Keane rolls his eyes while being serenaded by 'Roy Keane is magic' song, he loved it really

Manchester United fans serenaded their former captain by singing his iconic 'Roy Keane is magic' song after the club's 3-1 win against Arsenal, and fan footage suggests that deep down, he absolutely loved it.

Keane, who made 480 appearances for United during a trophy-laden 12 year spell, was on punditry duty for Sky Sports on Sunday afternoon as goals from Marcus Rashford [2] and Antony sealed all three points for his former side.

Old Trafford was understandably bouncing after the final whistle following Rashford's brace in the second half.

And to honour their former captain, thousands of supporters stayed behind to chant Keane's iconic song while host David Jones tried his best to deliver some analysis.

In the clip, Keane delivered a trademark eye roll as the 'Roy Keane is magic' song continued to ring around Old Trafford.

But in my humble opinion, the 51-year-old was trying his best to hide the fact that he was actually enjoying every moment. He even shared a joke with fellow pundit Paul Merson as fans continued to sing his name.

So what are the lyrics to the song, I hear you ask?

"Oh Keano's f*ckin' magic, he wears a magic hat and when he saw Old Trafford, he said I fancy that. He didn't sign for Arsenal or Blackburn 'coz they're s*ite. He signed for Man United 'coz they're f*cking dynamite."

Keane was on top form throughout Sunday's show, with a segment involving United playmaker Christian Eriksen being one of the standout moments.

In the aftermath of United's impressive 3-1 win against league leaders Arsenal, the pair bumped into each other as Eriksen took part in media duties on the Old Trafford pitch.

Keane, who has established himself as one of the most popular TV pundits, introduced himself by saying he had "no questions" for the Dane because he's "still upset" over his efforts against Ireland.

Eriksen replied: "Yeah, I thought so," before Keane hilariously hit back: "I'm still upset with you."

And it didn't stop there. Eriksen, who has been one of United's standout performers since his arrival from Brentford this summer, quipped: "It's a good night out as well, Dublin."

"...Yeah, I bet you did," Keane smiled. This is great.
