According to ESPN sports, the Englishman was full of eulogy for the Argentine despite playing alongside the Portuguese international.
While he described the Portuguese as a more ruthless finisher in the box, he said the Argentine would first torture his opponents before going on to finish them off.
“Ronaldo is ruthless in the box, a killer. But Messi will torture you before he kills you. With Messi you just get the impression he is having more fun.”
