Alvaro Morata is an experienced player who is still young and can make an important contribution by teaching tricks and tactics to younger players in order to create a long-lasting and experienced team that can compete in Serie A, and that's what they are doing.
Nobody says no, but he's obviously starting to get old too. You understand that to play in today's football you have to be in good shape otherwise you is simply out of the market. There's nothing wrong with that obviously, but if you want to be at the top you have to sign young players.
I do not think that it will be his physicality that will cause him to be not that great at Como. He played at Atletico Madrid, Real Madrid, Chelsea, Juventus, Milan, Galatasaray and now at Como. You do not see that many players who play in that many teams. They are all great teams because he is a great player, but that doesn't mean we are going to end up with him being that great at every place he goes to. Whatever is the reason, whatever happens, we end up seeing him change clubs all the time.
So I have no reason to believe he will leave Como, but all stats historically shows that he will be here for a while but then leave here too. Dude is not liked by any team he plays for, and always looked for a reason to be sent away.
