Should retire soon and not go the ronaldo route.retitre as a goat is better than choosing more millions he won't ever need
why should he retire? It's too soon. Time for retirement will be when he's Cristiano's age, not now. I do wonder if he's interested in going to the MLS for a year or two too, but I'd wager that he's not actually, since character wise he's not an attention seeking whore and maybe wouldn't even like the spectacle he'd be if he were to go play in the US. I think he'll stay in Europe for 2 more years and try to win one more CL if possible, and then head back to Newells for one final season, retiring at age 38-39.
As for now, he still has 2-3 more years in him at this level. Maybe not as a RW anymore though, but as a free role #10 like he was at the World Cup, absolutely. Attacking wise, he is still decisive enough to have a place in any top European team, that can support his off the ball walking and isn't obsessed with every player needing to run and press all the time (not a good idea, but there are teams like that).
