France coach Raymond Domenech is confident William Gallas will be fit for the World Cup.

The defender, whose contract with Arsenal expires this summer, has been troubled by a calf injury and is battling to make the plane to South Africa. Although he will not be risked in Wednesday's friendly against Costa Rica, his performances at a training camp in Tignes have cheered the French boss.

"After what we saw in training we can be optimistic," Domenech told TF1. "It is not the same in a game, however, and with the calf we must be careful. We want him to be ready for the World Cup."
