Marc Marquez's recent form makes ominous reading for his Moto2 rivals and the Repsol Suter star can further bolster his grip on the world title at Aragon this weekend.

Marquez - set to step up to MotoGP alongside Dani Pedrosa in the factory HRC team at the end of this season - has won five of the last six Moto2 races and was victorious at the Spanish circuit last year.

The Caixa Catalunya rider now holds a commanding lead of 53 points over Pol Espargaro with five races remaining.

Marquez has asserted his authority in Moto2 this year, although Espargaro's title challenge was badly hampered by a pair of non-finishes.

Espargaro finished second behind Marquez at the previous round at Misano, the third time this season he has had to settle for the runner-up spot behind his fellow Spaniard.

However, he has also beaten his title rival four times this season and finished on the rostrum in the past four races.

It would take a huge slice of misfortune for Marquez to forfeit his advantage at the top of the table, but the Repsol star isn't about to take his foot off the gas as he closes in on the title.

"Motorland Aragon is a track which went rather well for me last year and at which I felt very comfortable," he said.

"Let's hope that it is the same this time. We'll try to keep calm and have a good weekend in front of the fans.

"This track has a very technical first section, but the final sector is also very tricky. It is a circuit where you need to be good at cornering," added Marquez.

"The circuit is very close to Lleida, so I am sure that my friends, family and supporters will be coming along and that I will give my all to get the best result possible."
