He told Sky Sports: "He was the best player on the pitch. I think we're talking about a player who could go on to become one of the best-ever foreign players in the Premier League.
"Last season, we saw more than just glimpses, he looked like he was on the verge of becoming one of the best players in the Premier League last year before injury.
"Looking at him this season, he's going to be difficult to stop. Over the next four or five years if he produces regularly like he did today, we could be talking about him among some of the greats we've seen in Premier League history."
