Rossi '90 percent' sure to stay at Yamaha

The seven-time champion's current deal comes to an end at the end of the season, but both him and his team have made it clear that they are ready to extend their relationship.

Rossi said on Thursday that he is yet to decide if he wants a one or a two-year contract, but said the deal is likely to be announced soon.

"I have to speak with (Yamaha's racing department boss Masao) Furusawa during the weekend, but the atmosphere is very relaxed and I think it's possible to continue," Rossi told a news conference ahead of the Italian Grand Prix.

"It's not sure but it's more than 90 percent. Now we have to decide if one year or two years.

"The contracts today are quite big and there are a lot of difficult points to fix, but I think that (the announcement) will as soon as possible. For sure before the break, without any surprises."

The Italian arrives in his home grand prix as favourite after two consecutive victories this season have moved him into the championship lead.

Rossi has also won at the Mugello circuit for the past six years and is confident he will be able to extend his streak.

"We arrive in good shape, both with the tyres and with the bike so I think it's possible to be quite competitive. Also we need to wait to see the weather condition because Mugello is always difficult."
