Valentino Rossi's Peter Pan-like ability to remain competitive through his late thirties leaves fans and paddock insiders alike wondering if and when the nine-time world champion will retire. The subject comes up every two years or so, when Rossi's contract (and that of others) comes up.
Though it looks for now as if Rossi will continue, who to replace him with is an interesting question. Should Yamaha go for a veteran to partner Maverick Viñales? Or should they pick young talent for the second seat, and allow them to develop?
Last year, I spoke to three different factory bosses about how they viewed the issue, and how they go about developing talent for their own factories. The interview with Ducati boss Paolo Ciabatti was published last summer, but at the beginning of 2017, I spoke to Livio Suppo, then Repsol Honda team principal, about how his experiences of bringing on young talent, and the problem of finding a replacement for Valentino Rossi.
