Schu, Liuzzi, watch MotoGP at Mugello

(GMM) After attending the most recent Spanish and Monaco grands prix, Michael Schumacher this weekend switched his attention to the two-wheeled world of MotoGP.

The German, now an 'advisor' for the formula one team Ferrari following his sixteen year driving career, was spotted on the grid prior to motorcycling's Italian grand prix at Mugello.

The Autodromo Internazionale di Mugello, occasionally used for formula one testing, is owned by Ferrari.

38-year-old Schumacher was observed chatting with Ducati's championship leader Casey Stoner, and also Valentino Rossi, who rides for the Fiat-backed Yamaha team and in the past tested Ferrari's single seaters.

As in Monte Carlo last weekend, meanwhile, the seven time world champion turned down the press' requests for interviews.

Also at the Mugello circuit near Florence on Sunday was another notable MotoGP fan — Toro Rosso's Vitantonio Liuzzi.
