Manchester City fans were kept behind inside Old Trafford following their 2-1 win over Manchester United on Sunday.

And as they waited to be let out of the ground, came up with a song that not only celebrated their victory, but poked fun at their bitter rivals.

As almost everyone will know, United fans are regularly heard singing a chant to one of their former managers, Sir Matt Busby.

The song, which also references how many times they have won the title, goes as follows: "20 times 20 times Man United.

"20 times 20 times I say, 20 times 20 times Man United, playing football the Busby way."

Hijacking this song, and using it against their rivals to mock them after beating them in their own back yard, City fans incorporated Jose Mourinho's name into the lyrics instead.

"Park the bus park the bus, Man United," sang the Citizens supporters - as you can see in the above video.

"Park the bus park the bus I say, park the bus park the bus, Man United, playing football the Mourinho way."

As you can see, the song pokes fun at the Portuguese's style of play, after he set up his side to counter-attack against Man City.

Mourinho was previously criticised for setting his players up in a negative manner for United's other derby against Liverpool in October.
