McLaren debutant Jenson Button has revealed that he will be the last of the drivers to test the MP4-25.

Jenson Button will make his McLaren driving debut with the team at Valencia on the 3rd February, the last driver to drive the new McLaren in the three day tests.

Despite recent rumours of De La Rosa making a possible move to Sauber, he will be the first of three to test the new MP4-25, followed by Lewis on the second day and Jenson on the third.

Speaking at AUTOSPORT International, Jenson said:

“I am looking forward to it. It’s going to be the strangest day because it’s going to be one of the most important days in F1 in 2010, when we see where people stand, which cars are quick and which are competitive.”
