Usain Bolt and Piers Morgan have been going at it on Twitter about football

Piers Morgan will argue with anyone about Arsenal.

The journalist and TV personality is a die-hard Gunners fan and has been known to fight his club's cause against the likes of Alan Sugar, Gary Neville and Gary Lineker. He's found a new online enemy now in the form of the world's fastest man and Manchester United fan, Usain Bolt. Morgan got the back-and-forth underway by taking a dig at Manchester United's lack of exciting football as of late but Bolt came back quick as a flash, as he tends to do.

Or did @piersmorgan sleep any at all last night after that Arsenal lost

Not to be outdone, Morgan fired back by referencing the 3-0 drubbing handed out by Arsenal at the Emirates last month but, again, Usain had a comeback in the barrel.

Next time count all the titles @ManUtd has @piersmorgan — Usain St. Leo Bolt (@usainbolt) November 5, 2015
