Singapore GP: Jenson Button is still looking for 'balance'
McLaren's Jenson Button says he is not happy with the "balance" on his super-soft tyres, after finishing second fastest at Singapore Grand Prix second practice.
Button was 0.311 seconds behind Red Bull's Sebastian Vettel with Ferrari's Fernando Alonso third.
Button's team-mate Lewis Hamilton exchanged fastest times with Vettel for most of the two practice sessions, but finished fifth after running wide on the final corner on the super-soft tyres.
