Jenson Button bemoans red flags in Montreal
Jenson Button says the number of red flags in free practice hindered his McLaren team in trying out different set-ups for the Canadian Grand Prix in Montreal.
Button says in particular he was unable to test the super-soft tyres on a low fuel load.
The 2009 world champion expects the usual teams, Red Bull, Ferrari and Mecedes, to be their main competition over the weekend.
