Valentino Rossi optimistic on target date for return

Rossi has had four operations on his broken leg

Valentino Rossi says his recovery from a broken leg is going so well that his target of riding at the Czech MotoGP on 15 August is looking more realistic.

"I'm very happy with my recuperation - I didn't expect to feel this good after just a few weeks," said the Italian.

"If the rehabilitation proceeds without trouble, then my objective is to return at the Czech Grand Prix in Brno."

The Yamaha rider and reigning champion, 31, saw his title defence ended when he crashed at Mugello in Italy on 6 June.

Having missed races at Silverstone and Assen, Rossi will have also missed those in Spain, Germany and the United States if returns at the Czech MotoGP.

The seven-time champion added: "I am feeling a lot better and I'm starting to live a semi-normal life again, although for a completely 'normal' life I will have to wait until I'm back on my bike.

"I am walking with crutches and for the last few days I've been able to put my foot to the floor.

"I miss my bike, my team and the paddock a lot and this 'new' sensation is pushing me to get better as quickly as possible. "

During his absence, Rossi's ride will go to 41-year-old Japanese test rider Wataru Yoshikawa, who will make his debut for the Fiat Yamaha team at the Catalunya GP in Spain on 4 July.
