'We'll miss Lewis'

Jenson Button believes Lewis Hamilton's impending exit from McLaren will be "a big loss" to the team.u00a0Button 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 British 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."

Although Perez has acquitted himself well at Sauber over the last two years, the 22-year-old Mexican still remains an unknown quantity.u00a0Perez has conjured three superb podiums this season but his results have otherwise been sporadic, and notably since he was announced as Hamilton's replacement he has failed to score a point in three races.

Assessing Perez's potential, Button added: "I think Sergio will be fast, but I really don't know. u00a0"He's obviously unknown in a McLaren because he's not there yet. But it's a great opportunity for Checo, and I'm sure he will take it with both hands."u00a0
