PSG warmed up for next week's Champions League clash with Chelsea with a disappointing home draw against lowly Montpellier in Ligue 1.
Paris Saint-Germain maintained its 23-point lead at the top of Ligue 1 despite being held to a surprise 0-0 home draw by Montpellier.
A combination of wasteful finishing and inspired goalkeeping from Laurent Pionnier prevented Laurent Blanc's from taking full advantage of second-place Monaco being held to a draw by Caen on Friday.
The disappointing draw continues a league blip for the hosts, which began last weekend with their first defeat of the Ligue 1 season – a 2-1 result at Lyon.
