PARIS, March 24 — French Ligue 1 title contenders Lens yesterday objected to the potential rescheduling of their top-of-the-table clash with champions Paris-Saint Germain.

The two teams are due to meet on April 11, but that date became inconvenient for PSG after they thrashed Chelsea last week to set up a quarterfinal against Liverpool. That tie will be played on April 8 and 14, immediately before and after the scheduled Lens game.
