Jenson Button issues warning to title rivals

Jenson Button is revelling in his latest fight for the Formula One world title and has warned his rivals "there is more to come".

Button has had to settle for second best in the last two races in Turkey last month and Canada on Sunday as McLaren team-mate Lewis Hamilton grabbed the glory with victory.

But back-to-back one-two finishes means there are just three points separating the duo at the top of the drivers' standings, and with McLaren 22 points clear of Red Bull in the constructors' table.

No-one could have envisaged that being the case prior to the race in Istanbul just over a fortnight ago, least of all Button who is happy enough with second in the championship and being on the tail of Hamilton.

"If you had told me before Turkey we would be in our position now, it would have been quite hard to believe," said reigning champion Button.

"Naturally, with those one-twos, I'd rather have been in front, but I haven't been, yet I've still picked up some really good points."
