But the TV personality got more than he bargained for when the gold medal winning athlete gave his stinging reply.The clash came after Olympics star Bolt posted a pic of himself on Twitter looking quizzical at a podium and asked his followers to caption it.
Morgan soon replied, with a caption that suggested Bolt was blasting his own side, saying 'Will Manchester United ever play entertaining football again?'
But the journalist would soon be eating his words when his team of choice, Arsenal, got thrashed 5-1 by German side Bayern Munich.
So Bolt shot back with "did Piers Morgan sleep at all last night after that Arsenal loss."
Determined to have the last word, Piers said he "got to sleep by counting all the goals Arsenal scored against United last month".Then Bolt offered another sleeping-aid, saying "next time count all the titles Man United has".
Morgan has a history of clashing with the stars on social media, getting into rows with Niall Horan, John Cleese and Alan Sugar.Follow Me On Twitter & Instagram: @effiongeton
