Marc Marquez says he needs to win two more MotoGP races at least this season in his quest to clinch a third premier class title.

The Repsol Honda rider maintained a healthy advantage of 43 points at the top of the standings over Jorge Lorenzo after finishing fifth in Austria last weekend.

Marquez, who suffered a dislocated shoulder in a heavy fall at the Red Bull Ring, has also stated the importance of finishing consistently inside the top three for the remaining eight races as the 23-year-old looks ahead to this weekend's 11th round of the championship at Brno in the Czech Republic.

"We couldn't fight for the podium in the race but now we are in Brno it looks like it will be better for us. It was an important fifth place especially because Lorenzo is the rival that is closer to us and he only took five points more than us and Valentino [Rossi] only two, so I am happy for this because it was a circuit where we could lose many points," he said.

"Here we will try to fight for the podium and the victory and if it is impossible to win, then we will try to lose not many points to both Yamaha riders. Of course the position will be important but in the end you must also be consistent on the podium. I know that in my case if I want to win the championship I need to win a minimum of two races more because both Yamaha riders are pushing a lot.

"The shoulder is not 100 per-cent but it will not be problem for this weekend. Everything looks fine at the moment and I think it will be a better circuit than Austria because with Le Mans, it is the two circuits where we struggle more," added Marquez.

"Since 2013 I feel good here at this circuit in MotoGP and already last year I did a good race; Lorenzo was extremely fast but we were able to stay close with all the problems we had last year. We will try to be closer to fight until the last lap and we will see."

Ducati's one-two in Austria with Andrea Iannone and Andrea Dovizioso played into Marquez's hands, preventing Movistar Yamaha riders Jorge Lorenzo and Valentino Rossi from securing more points.

Marquez admits that Ducati's resurgence could prove beneficial in his attempt to seal the title, but the Spaniard remains uncertain over whether or not the Italian duo will be able to compete at the same level consistently during the final half of the season.

"We will see here if Ducati confirm there level of Austria and it will be big help for me or the other side, because they can take a lot of points. In Austria it was a big help because I lose less points but here it can be the opposite," said Marquez.

"Honestly speaking I think that they have a very competitive bike but I don't know if they will be constant at all the circuits. When we started in Qatar they were very competitive and very fast.

"In Spielberg it was a special track and maybe here again they are fast, but then we will see. But for the championship if they are fast it will be better for me."

Marquez and Lorenzo have both won three races so far this season, with two victories for Rossi and one each for Iannone and Jack Miller.
