At the Raymond-Kopa Stadium, Di Maria finished a superb curling free-kick in the 28th minute. Angers captain Cheikh Ndoye’s goal in the 39th minute was disallowed due to a foul by Famara Diedhiou on PSG defender Serge Aurier.
The reigning champions didn’t stay at the same level early in the second half, and their goalkeeper Kevin Trapp was forced into a brilliant save on Ndoye’s powerful header.
It was Di Maria again. The Argentine international converted Lucas Moura’s pass into a game-winning goal from the left flank with six minutes remaining.
Monaco, who beat explosion-hit Bundesliga side Dortmund in midweek’s Champions League, can regain a three-point advantage as they will host relegation-threatened Dijon on Saturday. Third-placed Nice will face Nancy at home.
