Jenson Button believes McLaren are closing the gap on Red Bull despite the dominance of Sebastian Vettel.
Vettel has five wins and five poles from the last six grands prix stretching back to the end of last season.
Button said: "When somebody makes a start like Sebastian has, it's tricky. We've only had two races and he's already a race win in front of me. I feel we are closing in on Red Bull... there is more to find with the set-up of the car."Reuse content
