Skipper for Club and country, Hugo led France to a 1-0 win in Bulgaria in European qualifying Group A.
The pressure was on with rivals Sweden racking up an 8-0 win against Luxembourg but France held on to top spot thanks to Blaise Matuidi's early goal.
Hugo only had one save of note, and it was quite a save. He initially spilled Todor Nedelev's shot in the wet conditions but sprung up off the floor to keep out Georgi Kostadinov's follow up header from point-blank range. Moussa remained an unused substitute in Sofia.
Victory in France's last Group A match at home to Belarus in Paris on Tuesday evening will see Les Bleus finish top and qualify for next summer's World Cup finals.
