Jenson Button says Lewis Hamilton exit a 'big loss' for McLaren

Jenson Button believes Lewis Hamilton's impending exit from McLaren will be "a big loss" to the team.

Button has previously made it clear he has enjoyed pitting his wits against a fellow world champion in Hamilton these past three years, helping to make him a better driver.

Although there will be no second crown for either man this season, a 24-point gap between the English duo means Hamilton is set to leave for Mercedes with a 2-1 victory in their inter-team rivalry based on total points at the end of the season.

Rising star Sergio Perez may have been recruited as replacement, but the 32-year-old Button cannot help but feel Hamilton's departure will be felt by the team.

"With Lewis leaving, obviously the team loses a very fast driver," said Button.

"He's a guy that's achieved a lot with the team, wins and obviously a world championship - the last guy to win a world championship for the team.

"It is a big loss, but things change and you learn to move on and adapt. It's definitely not the end of two strong drivers at McLaren."
