Paris Saint-Germain moved 22 points clear at the top of Ligue 1 as first-half goals from Thiago Silva and Maxwell secured a regulation 2-0 victory over Bastia.
The result in the first league match back following the mid-season break extended the reigning champions' unbeaten league run to 29 games as they canter to a fourth successive title.
But Ghislain Printant's men are yet to win on their travels this season and rarely threatened to improve upon that record once Thiago Silva headed the home side in front after 29 minutes.
And, after Maxwell doubled PSG's lead just before the break, an eighth home league win of the season for Laurent Blanc's side was all but assured.
Angel di Maria's corner reached Thiago Silva, who had ghosted in at the far post, and his header had already crossed the line before Thiago Motta made sure by scrambling it into the net.
Di Maria again claimed the assist with a delightful flighted throughball and Maxwell finished in style with a stunning angled volley.
As the second half progressed, PSG opened up the Bastia defence on an increasingly regular basis, with Zlatan Ibrahimovic, Serge Aurier and Lucas Moura all seeing goalbound efforts blocked.
Sebastien Squillaci did cause a rare anxious moment for the home defence when he pounced upon a fumble by goalkeeper Kevin Trapp on 70 minutes, but the danger was cleared and normal service was swiftly restored as substitute Ezequiel Lavezzi came within inches of making it 3-0 with a curling effort from just inside the box.
Squillaci almost inadvertently added a third for PSG in the 90th minute when he headed Lavezzi's cross against the frame of his own goal.
