Mane was heavily linked with a move to Old Trafford before leaving Southampton to join Liverpool in 2016.
Since moving to Anfield, he has won the Premier League, Champions League, Club World Cup and the Premier League Golden Boot – becoming one of the most feared attackers in Europe.
Wright, the former Arsenal striker, is a big admirer of the Senegal international and insists he is ‘now easily one of the best in the world’.
And he believes Manchester United lived to regret failing to secure his signature four years ago.
‘Remember Man United were all over him, you know,’ Wright said on his new podcast Wrighty’s House.
‘I think they spoke to him but he said no. Manchester United weren’t right for him.
‘Again, you feel like Man United made a big mistake by not making that signing. By not being in the position to make that signing.
‘He’s now easily one of the best in the world.’
