Hamburg - Formula One driver Timo Glock believes there is a good chance of FIA ruling in favour of the diffusers being used by Williams, Brawn GP and his Toyota team. Motorsport's ruling body will hear the protests lodged by BMW- Sauber, Ferrari and Red Bull against the controversial designs on Tuesday in Paris.

"Three teams had the same idea. This shows that they believed it was legal from the start," Glock told the German ZDF national television network.
