Marc Marquez not concerned by Jorge Lorenzo's MotoGP title surge

Marquez has won only once in the past six races - while Lorenzo has triumphed four times - and was also disqualified for a pit infringement at Phillip Island, meaning a 44-point lead over Lorenzo has been trimmed to 13 with one race left.

The Spanish rookie admits he was unable to live with Lorenzo's pace last time out at Motegi, but says his desire was also limited by his still-healthy championship margin.

"In the race [at Motegi] I had good confidence from the beginning, but then every lap I felt more on the limit," he said.

"I tried to overtake Jorge but I saw that there was too much risk and then in the end when he pushed a little bit more I felt I was too much on the limit.

"I had two big moments and then I said 'OK, it's much better to take 20 points for the championship'.

"Now Valencia will be interesting. I must just concentrate on my job, on my bike and try to do my best.

"We cannot forget that it's my first season and that [the title] was not the target but, anyway, we will try 100 per cent to get it."

Marquez has previous form at Valencia, having pulled off a remarkable victory from the back of the field in his 2012 title-winning Moto2 campaign.
