Mo💟toGP title leader Jorge Lorenzo appears open to the possibility of former team-mate Valentino Rossi returning to Yamaha in 2013.

Rossi requested that the wall dividing the Yamaha pits in 2008, due to a difference in tyre manufacturer for Rossi and Lorenzo, remain in place even after MotoGP switched to a single supplier in🌠 2009.

It seemed to su🃏m up the frosty relationship that existed between Lorenzo andജ Rossi, although the Spaniard - Rossi's toughest ever team-mate - always felt it was unnecessary.

"In💞 the case Valentino joins again Yamaha there will be no wall from my part, of course," said Lorenzo at Assen on Friday. "I always thougওht it was not necessary and I still believe that."

Lorenzo, world champion during Rossi's injury-interrupted 🌄final M1 season in 2010, recently extended his Yamaha c𝐆ontract until the end of 2014.

But the Spaniard st𝓀ated that Yamaha will decide the identity of his team-mate.

"Valentino is a good rider, he has won a lot of titles and a lot of races," he said. "I think he can still be competitive in MotoGP sꦫo he is an interesting rider for Yamaha. Of course there are other riders that could be good for them also, so they wil𓂃l have to decide."

Rossi has taken just two podium finishes since leaving Yamaha for Ducati. The Italian is being linked with a possible return to Honda as well as Yamaha,💮 but insists his objective is t𓄧o continue with Ducati.

Ben Spies currently occupies the second factory M1 seat, bu🌃t is just eleventh in the championship.

MotoGP rules announced at Assen on Friday confirmed that each manufacturer is officially limited to four bikes, two official and two satelitte, reducing the chan🎉ces of Rossi setting up his own team.
