Hasn't shown that he is old. If you look at the game Ronaldo showed, Martinez is very aware of how to take advantage of Ronaldo's greatness. The Portuguese team seems to know what they have to do for Cristiano Ronaldo so that Ronaldo does not waste the opportunity to open the score.
The jump is still okay. The kick is still okay. Body is still okay, it's just the running speed that has reduced from Ronaldo.
In the final against either Spain or France, we will see what Ronaldo can do for Portugal.
Despite age, it is still good, and it's great that he supports such a high level of the game. Recently, I read somewhere that Ronaldo could return to Europe, but I think that this is all at the level of rumors, because at this age it is unlikely that anyone will be ready to sign a long contract, and even moreover, it will be very difficult for clubs to compete with Saudi Arabia in payment, so I think that he will continue to play there.
Portugal showed that they are very good now. Today I would like France to win, they have a very good composition, but for some reason the results are weak especially in the attack.
