Jorge Lorenzo admits his back-to-back wins at Motorland Aragon took him by surprise as the Movistar Yamaha rider mulls over his prospects of a third straight victory on Sunday at the Spanish track.

Lorenzo won on home turf at Aragon in 2014 and 2015, even though the circuit has not traditionally been one of the best matches for the Yamaha M1.

The reigning MotoGP world champion is without a win this season since Mugello in May and Lorenzo is eager to get back on track as he attempts to close the gap on team-mate Valentino Rossi in third place in the standings, who is 18 points ahead.

"In the last two years here I won: in 2014 in strange conditions and last year in dry conditions I could win the race. Normally it is not a track that suits the Yamaha, but in the last two years it is amazing we are competitive and I am looking forward to see tomorrow how is the performance," said Lorenzo.

"[The circuit] has a very long straight that comes from a very slow corner, so acceleration and wheelie and also top speed is something that will be very important. And then it is a very flowing track with a lot of different corners that can suit quite well our chances."

Lorenzo remains focused on winning more races during the final five rounds of the championship and finishing above Rossi in the final table.

"Yes, [I want to] win as many races as possible and try to finish second. Second is always better than third and third is better than fourth, so we will try to finish second."

After qualifying on pole in the previous round at Misano, Lorenzo was unable to mount a serious bid for victory as Repsol Honda's Dani Pedrosa and Rossi both finished ahead of him in first and second places respectively. The Mallorcan admitted he was disappointed overall with third and said he was a few tenths short of the pace he needed to be a threat.

"Yes I was a little bit disappointed because I expected to fight for the win a little bit more, even if I knew I didn't have the best pace of my career in the practice. Anyway, I didn't expect Dani to be so strong and he was really fast and he overtook us very quickly. I needed one or two tenths of pace that I didn't have."

Following the race, Lorenzo engaged in a verbal spat with Rossi, accusing his team-mate of being overly aggressive when he made an overtaking manoeuvre during the race. Having since seen video footage of the pass, the three-time premier class champion said his view remained unaltered.

"On the bike I couldn't see his line and on the video I could see his line, so yes - I still believe in that opinion," said Lorenzo, speaking at the pre-race press conference at Aragon.

Rossi had laughed off the claim in the post-race press conference at Misano and said he 'did not agree' with Lorenzo's assessment of the overtake.
