PARIS, April 19 — Paris Saint-Germain could wrap up the Ligue 1 title as early as next week, which would secure the first trophy of what they hope will be a historic treble after their comeback victory over Barcelona in the Champions League.

Luis Enrique’s men host a resurgent Lyon on Sunday, knowing victory may give them the chance to clinch the title with four games to spare when they visit Lorient on Wednesday.
