(Reuters) - Nice manager Christophe Galtier celebrated a winning return to his former club Lille on Saturday, as they hammered the French Ligue 1 champions 4-0 at Stade Pierre Mauroy for their first victory of the campaign.

Nice's Danish forward Kasper Dolberg scored in either half, including a first-minute goal from close range, while midfielder Hicham Boudaoui's early strike and the impressive Amine Gouiri's first-half penalty completed the rout.
