The former Barcelona defender put in an incredible display at Stade Louis II, setting up Gonzalo Higuain to break the deadlock with a back-heel.
He was instrumental in his side recording a comfortable 2-0 win in the first leg of their Champions League semi-final with the Ligue 1 giants.
And both Gary Lineker and Glenn Hoddle were in full agreement with Ferdinand, with the former asking: “Why did Barcelona let Alves go?”
Speaking on BT Sport after the game, Ferdinand said: “He’s still the best in the business bar none.
“He is the best with the ball, he defends when he needs to, you saw against Barcelona, he had Neymar in his pocket.
“He does every part of the game that you want from a right-back in modern day football.”
Hoddle added: “You wonder whether Man City are looking at him.
“I don’t know about his age, but if they’re looking for a right-back why don’t they go and get him? He’s fantastic.”
