Aug 15 (Reuters) - France's World Cup prospects have suffered with the injury to flyhalf Romain Ntamack but coach Fabien Galthie has several options to replace him, including Matthieu Jalibert, in-form Antoine Hastoy or even a switch from fullback for Thomas Ramos. It is a combination capable of devastating effectiveness, at eye-jolting pace and with a Gallic flamboyance, and the fact that France cannot use Ntamack will weigh heavily on the rest of their World Cup preparations. He won the European Champions Cup with La Rochelle this year but has won only three caps for France and played a total of 96 minutes of test rugby. France name their World Cup squad next Monday.
