Valentino Rossi doesn't expect any psychological advantage from halting team-mate Jorge Lorenzo's title momentum at Silverstone.

But the 2015 championship has probably become a blue-on-blue Movistar Yamaha battle, with Marc Marquez slipping 'very far' behind.

Lorenzo had beaten Rossi at the last two rounds to pull level with the Italian at the top of the championship standings.

The Spaniard then looked set to take the title lead outright as he outpaced Rossi throughout practice and qualifying for the British Grand Prix.

But wet weather played into Rossi's hands on Sunday, when The Doctor claimed his fourth victory of the season while Lorenzo was off the rostrum in fourth.

Rossi is thus twelve points in front with six rounds to go. But that is all it means.

"Unfortunately it is not important [psychologically], zero, because Jorge [taps hand on table] is strong," Rossi said. "So it is an important twelve points, but a psychological advantage - not a lot unfortunately.

"It is important for sure to remain on top. Because I have been first from the first race and Jorge was one point behind me after Barcelona. Then he go down, then he arrived equal with me after Brno. But never in front. Never one point in front.

"So to re-open the gap is fantastic also because on paper this is a track where Jorge can beat me. But just this. Twelve points, six races to go and a lot of tracks where Jorge is very, very, very strong. So it is very open."

Indeed, Rossi felt the race was more significant in terms of reigning double champion Marc Marquez, whose fourth DNF of the season has all but extinguished his already slim title hopes. The Repsol Honda star is now 77 points behind with a maximum of 150 still available.

"I think it is more important with Marquez because with this zero he is not finished [in the title fight], but now he is very far," Rossi said. "This is very important to have a big advantage on Marquez. But in the case of Jorge it is just twelve points."
