The problem for Schumacher is that he doesn’t have a few years to spare to grow. He’s one of the great drivers of the past, but to me he’s just clogging up space for a young driver right now. He needs F1, I don’t really know if F1 really needs him anymore though.
He can’t get into his normal routines of before (testruns for hours and hours) and won’t be able to get into that same scheme next year. In a sport that has so little seats available, teams should think twice before bringing back old glories. For the sake of the youngsters, but just as much for the sake of the older driver that returns.
