Di Maria scores and George Weah’s son makes debut in PSG win
Two minutes after halftime, Di Maria ran onto a clever flick from Julian Draxler and dinked the ball over goalkeeper Erwin Zelazny, who rushed off his line. It was his 13th goal since January, and he looks certain to start against Real Madrid in the last 16 of the Champions League on Tuesday.
PSG trails 3-1 from the first leg in Madrid.
Attacking midfielder Christopher Nkunku wrapped up the win with a well-taken goal in the 77th, cutting inside a defender and rifling in a shot.
Moments later, 18-year-old striker Timothy Weah - the son of Liberia President and former PSG striker George Weah - went on for midfielder Giovani Lo Celso. He almost scored after going clean through right at the end, but Zelazny denied him.
PSG remained 14 points clear of second-place Monaco with 10 games left and is coasting to the title. It was all very comfortable against 18th-placed Troyes, even with PSG's three best forwards missing.
''We didn't concede any chances and closed them down well,'' PSG coach Unai Emery said. ''We were patient.''
Brazil star Neymar had an operation on Saturday to repair a broken toe in his right foot and could be out for up to three months. With one eye on Madrid, Emery left out Kylian Mbappe, top scorer Edinson Cavani, and key midfielder Marco Verratti.
''We managed to rest a few players,'' Emery said. ''We're ready for Tuesday.''
PSG dominated the first half but could not find a way past Zelazny.
He made several smart saves, including on two Lo Celso shots from outside the penalty area and an overhead kick from Nkunku.
Winger Wahbi Khazri scored his ninth goal in 17 games as Rennes won at Amiens 2-0.
Khazri struck close to halftime and Senegalese forward Ismaila Sarr got the other late on.
