Youngster Senny Mayulu's first Ligue 1 goal set PSG on their way before Marco Asensio, Bradley Barcola and Lee Kang-in also found the net in the rain at the Parc des Princes. Sekou Mara and Pape Diong were on target for Liam Rosenior's Strasbourg, but the defeat means the side from Alsace have still never won away to PSG in 34 attempts. Monaco's 0-0 draw at home to Lille on Friday had given PSG the opportunity to go back to the summit and they seized the opportunity despite coach Luis Enrique rotating his squad with an eye on Tuesday's Champions League clash with PSV Eindhoven.
Ousmane Dembele, Achraf Hakimi, Fabian Ruiz and captain Marquinhos were among the players left on the bench with Mayulu one of five players aged 20 or under in PSG's starting XI. The 18-year-old hit the post before he opened the scoring.
