Mar.7 (GMM) Sergio Perez has felt the added pressure of stepping up the F1 grid for 2013.

Formerly the surprise podium-getter in a Sauber, the 23-year-old has now been signed up by McLaren, to replace the ultra high-profile Lewis Hamilton.

"Of course the pressure is higher now," the Mexican is quoted by Speed Week, as he represented his new employer at the Geneva motor show.

"But I have no problems with it.

"Anyone who can't handle pressure should not sign for McLaren," added Perez.

According to most pundits, Perez has had a mixed first winter with the famous British team, complaining about "extreme" tyre degradation and a difficulty adjusting to the new MP4-28.

"Of course I would have liked to collect more information before going to Australia," he admitted.

"Some days it was cold and really difficult to learn about the car," said Perez.

"But I don't know anyone in the pitlane who had carefree winter testing.

"So it's the same for everyone, not a disadvantage for us."
