Keys told beIN Sport: "We all know that he has been one of the best of his generation. There is only one other to match, or maybe better than what he was capable of doing, Itâs not Ronaldo anymore. It is a long, long way from being Ronaldo anymore. There are times when Iâve been watching him and thought - he could go on in this tournament to prove me entirely wrong - but running is not his friend.
"The other thing that bothers me is, as they come into the tournament, everythingâs fine. The minute he comes off or doesnât start, big trouble. Theyâre like boxers, again players. They never quite know when the time is right to call it a day and I think heâs in that category."
