Roy Keane had Jurgen Klopp in fits of laughter on the Old Trafford side line as he brought up an old argument between the pair.
Keane and Klopp clashed back in September 2020 while Keane worked for Sky Sports covering Liverpool's clash against Arsenal.
Liverpool would go on to win 3-1 with goals from Sadio Mane, Andy Robertson Diogo Jota but Keane brnaded their performance as 'sloppy'.
