Consequently, he will not be available for the club's return match against Real Madrid in the Champions League and with the Parisians seeking to overcome a 3-1 deficit, Henrique admits he will be sorely missed.
The Champions League holders defeated the French side 3-1 at home in the first leg of their round-of-16 tie last month and are now due a visit to the Parc des Princes, where the second leg will be played out on Tuesday.
They will, however, have to do so without the 26-year-old attacker, who underwent successful surgery on a broken foot on Saturday, with PSG forecasting the Brazilian's absence from training to be around six weeks.
"I want the players to be ready (against Real)".
"We managed to rest a few players", Emery said. "He's got both the confidence and the desire".
Troyes goalkeeper Erwin Zelazny produced a series of saves to deny Di Maria, and then Giovani Lo Celso twice in the first half, but the home goal was breached after a defensive lapse on 47 minutes.
Zelazny was finally beaten two minutes after the restart as Di Maria raced on to Julian Draxler's through-ball and finished low into the bottom corner. Alves netted the rebound but it was ruled offside.
PARIS (AP) - Angel Di Maria maintained his rich scoring form and George Weah's son made his debut as runaway French league leader Paris Saint-Germain won at Troyes 2-0 on Saturday.
On Friday, Rony Lopes scored his sixth goal in seven games as Monaco came from behind to beat Bordeaux 2-1 to tighten their grip on second place, with Marseille and Lyon not in action until Sunday.
