Graeme Souness has doubled down on his claim that Casemiro is not world class.
He acknowledged that Casemiro has had a striking impact on the United side, writing that 'he's the single biggest reason why the team have settled down'.
Gary Neville, however, questioned Souness' claim, heaping praise on the 30-year-old.
In a live TikTok video at Anfield before Liverpool hosted Man United on Sunday, Neville asked Souness to explain his opinion again.
