He should have stayed retired and stayed with Ferrari, it was a bad ego move on his part. You know, he has helped in the development of a shitload of past and present Ferraris? Dude, was set for life, just continually fine tuning Ferraris, while being a technical advisor to Ferrari SpA.
He's still set for life , he's still relatively competitive considering how fast the sport progressed , his age and the fact that he hasn't set foot in a car in a long time , it took him years to soft the Ferrari out and once they did he was unstopable , in a top tier car he would still be winning but he's doing damage to his legacy
I've always like Schumacher I was a fan since his Benneton days and I've always been a huge Ferrari fan so when he switched I was excited , but Luca was pissed he choose to come back with Mercedes and not Ferrari , Mercedes wants a German car , driver ( team ) and World champ in the worse way , we'll see what happens
