Zlatan in his 30s has arguably played some of his best football. Now this is no comparison, more of a case study that it can happen. Rooney has not shown real form for about 3 seasons so it feels unlikely that it will suddenly come back, but that said a new routine, a change of fitness programme, maybe a reduction in pressure and competition and Rooney might regain some form. So the question how would you feel if Rooney found some 9/10, 11/12 form and scored over 30 goals in each of the next 3 seasons. I'll leave it at 3 seasons as at 35 few go on from there and it looks an ask for Rooney to even get that far. So let's call it him making an unlikely Everton ton? I personally would be thrilled and happy for him. It would be sad he couldn't find that form for us, but he is a legend and it'd be nice to see his career be more than it has been in the last couple of years. The main disappointment would probably be the hindsight of saying how do we have a player of his history, marketability and potential skill and get no money for him, unless of course you believe the £25m valuation which would be fair.
