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.

Vincent Janssen, currently on loan at Fenerbahce in Turkey, played 68 minutes as Holland beat Belarus in the same group.
Holland are now three points behind second-placed Sweden and the two teams play each other in the final group game in Amsterdam on Tuesday - Holland need to win and make up 12 goals on goal difference.
Belgium are already making plans for Russia having secured qualification last month and Jan Vertonghen - who scored one of the goals that rubber-stamped top spot in Group H - was on target again in a 4-3 win against Bosnia & Herzegovina.
On the day he joined Jan Ceulemans as the most-capped Belgium international on 96 caps, Jan tapped home from a corner as the Red Devils made it eight wins and a draw in their nine matches so far. Jan and Toby Alderweireld completed the 90 minutes at the Grbavica Stadium.

It's D-Day for Christian Eriksen and Denmark's World Cup hopes.
Christian has inspired the Danes to four successive wins - scoring in each - in Group E of World Cup qualifying, including crucial victories against leaders Poland and closest rivals Montenegro.
Now it's crunch time as Denmark conclude the group with a home match against Romania while Poland face Montenegro in Warsaw.
Denmark need a point to clinch second place and to be in the shake-up for a play-off spot - eight of the nine best runners-up go into the play-offs - but will aim to beat Romania and hope Montenegro topple Poland. Denmark and Poland are level on goal difference so a Denmark win and Poland defeat will send Christian's team to the finals.
Elsewhere, Dele Alli, Eric Dier, Harry Kane, Kieran Trippier and Harry Winks are with England for their final qualifying match in Lithuania (5pm). Harry scored the winner against Slovenia on Thursday that clinched top spot and a place in Russia.
