Factory Yamaha's Jorge Lorenzo will concentrate on winning the MotoGP world championship and beating new/old team-mate Valentino Rossi will simply be a sideline, the Spaniard said today.

Speaking at the Indianapolis pre-event press conference, the championship leader said it would be a pleasure to have The Doctor at Yamaha once again - this time without a wall - but his main focus is on the world championship crown.

"I think it's interesting to see how we can handle again Valentino and me on the same team and the same bike. I'm very interested to see what is going on. And for me, it's a big pleasure to be teammate with him again," said Lorenzo.

"Maybe one of my challenges will be again to beat Valentino, but it's not the main one. The main one is to again be World Champion this year and the next two years.

"I never cared about my teammate, I will not care in the future. For me it is a pleasure to be again with Valentino, two more years with the same bike. So for me, everything is positive. Yamaha never have a number one rider given the best performance bike or the best pieces, no. So it will never be different, I think."
