Paris Saint-Germain recovered from their midweek Champions League heartbreak as they continued their march towards a first Ligue 1 crown in 19 years with a 1-0 win at basement side Troyes on Saturday.
Blaise Matuidi broke the deadlock at Stade de l'Aube on 65 minutes with the game's only goal as PSG opened up a provisional 10-point gap over Marseille, who travel to in-form Lille on Sunday, at the top of Ligue 1 with just seven games remaining.
The possibility of a European hangover loomed large following Wednesday's 1-1 draw with Barcelona at Camp Nou that saw the Parisian outfit bow out of the quarter-finals on away goals, especially with the absence of the suspended Zlatan Ibrahimovic, without whom PSG had failed to record a league victory this term.
Kevin Gameiro, making a rare start in place of Ibrahimovic, squandered an excellent chance to put the visitors ahead inside five minutes as he was thwarted by Troyes goalkeeper Yohan Thuram after escaping the last defender.
The hosts almost grabbed an unlikely lead shortly after through Stephane Darbion as his angled attempt struck the frame of the PSG goal before Salvatore Sirigu was forced into a pair of smart saves to repel both Fabien Camus and Benjamin Nivet.
Thuram then had to be alert to deny Ezequiel Lavezzi just after the restart, while Gameiro's day was brought to an abrupt end on 64 minutes as he was hauled off with Thiago Motta taking his place.
A visibly frustrated Gameiro made his displeasure known, muttering: "It's always the same thing, always the same thing," after blanking Ancelotti on his return to the dugout.
His uncharacteristic outburst could not have proved more ill-timed though as Matuidi, who missed the second leg in Barcelona through suspension, put PSG ahead barely 60 seconds later.
Gregory van der Wiel's hopeful cross eluded the home defence, allowing Matuidi to sneak in at the far post and slot beyond a helpless Thuram for his fourth goal of the campaign - and the second this season against his former club.
Javier Pastore rifled in a low strike that Thuram expertly repelled with a strong right hand as the visitors looked to turn the screw.
The home side refused to surrender, however, but they were unable to find a way past the excellent Sirigu as the Italian tipped over a late long-range strike from Camus to record a remarkable 20th clean sheet of the season.
