Paris Saint-Germain star Dani Alves is a player known for giving his all for the side, and the Brazilian right-back showed he is more than willing to jump into hard positions in Tuesday night's 4-1 Coupe de France win over Souchaux.
PSG goalkeeper Kevin Trapp was sent off in the last minute, with right-back Dani Alves going in goal for the final seconds.
PSG had used its three substitutes, so after a few moments of deliberation the gloves were handed to a startled-looking Alves, who has forged a stellar career over the past decade as one of the world's best right backs.
PSG was ruthless up front, even without the rested Neymar.
"The goal today was to advance beyond this round of the French Cup without injuries", said Emery, whose side travel to Real Madrid next week for the first leg of their Champions League last 16 tie. Videos of the players partying late - less than 48 hours before the game - circulated on social media.
Sochaux captain Florian Tardieu suggested pre-match that PSG players attending a birthday party for Neymar in Paris on Sunday demonstrated a lack of respect for his Ligue 2 side, but PSG skipper Thiago Silva denied that was the case.
"We're very happy with (Di Maria)", added the Spaniard, who has seen the revitalised Argentine score nine goals in 10 matches since the turn of the year.
He headed in a Kylian Mbappe cross in the first minute, before Florian Martin's half-volleyed equaliser.
The Argentina global caught Sochaux keeper Lawrence Ati-Zigi off guard at his near post with a precise left-foot finish after 59 minutes and then scored on the rebound after Cavani's effort was parried into his path three minutes later.
Meanwhile, there were two other hat tricks as Marseille won 9-0 win away to second-division Bourg-en-Bresse.
Despite making six changes to the starting XI, Marseille ended the tie as a contest with early goals from Luiz Gustavo, Dimitri Payet, Ocampos and Mitroglou.
