Both Felipe Massa and Fernando Alonso confirmed after the Spanish grand prix that they made contact whilst battling for the lead at the first corner.
McLaren’s Alonso, who fell to fourth after running through the gravel and ultimately finished third, seemed unhappy with race winner Massa’s behaviour.
“I thought I was in front but obviously he (Massa) didn’t think so,” the Spaniard said after the race, adding that the light clash damaged his bargeboard.
Massa protested: “It was a risk for both of us, but the first corner is important — you don’t want to lose like I lost in Malaysia.”
