Monaco remains top of Ligue 1 after the club's star striker rescued a point against the reigning champion at the Parc des Princes.Paris Saint-Germain missed the chance to go top of Ligue 1 after recording a 1-1 draw with Monaco.
Zlatan Ibrahimovic gave the French champion the lead after a matter of minutes but Radamel Falcao rescued a point for the table-topping side to ensure that both sides' kept their unbeaten records in tact.
PSG coach Laurent Blanc made just one change from the side that won 4-1 at Olympiacos on Tuesday, with Ezequiel Lavezzi coming in for Lucas Moura.
Claudio Ranieri, meanwhile, kept faith with the starting XI that ran out a 1-0 winner at home to Lorient last weekend.
The home team made a near perfect start, Ibrahimovic getting across Danijel Subasic's dive at the near post to volley home Maxwell's inviting left-wing cross from six yards.
The club was dealt a blow soon afterwards, though, when captain Thiago Silva was forced off with what looked like a hamstring injury, and the visiting side took advantage to equalize just six minutes later.
Joao Moutinho was the architect when he whipped a ball in from the left side, and Falcao got across his marker at the near post to touch home at full stretch.
Ibrahimovic threatened again in he 24th minute, chesting down a high ball expertly before firing a volley from distance just wide.
Meanwhile, Yannick Carrasco should have made Salvatore Sirigu in the PSG goal work five minutes later, but he sent his shot well over after a loose ball fell kindly for him inside the area.
The game became increasingly open as the half wore on, with Edinson Cavani running onto Ibrahimovic's flick before firing across Subasic and wide of goal.
Ibrahimovic should have given his side the lead for a second time in the 37th minute, but the Sweden international headed Lavezzi's free kick over the crossbar when unmarked eight yards from goal.
A minute later, Falcao sent a 25-yard free kick narrowly wide as both sides looked to take an advantage into the break.
Ibrahimovic again almost provided it with two minutes of the half remaining, but this time he sent his deft chip wide of the post with Subasic stranded.
There was still time for Cavani to flick a header wide in first-half stoppage time as PSG ended the half the stronger.
Things were more subdued in the second half, but six minutes after the break Lavezzi and Ibrahimovic combined again, only for the latter's back heel to be denied by a sprawling Subasic.
Carrasco then wasted a good opening for the visiting team five minutes later, volleying wide when in space 12 yards out.
Both sides continued to push for a winner, but their respective defenses stood firm as the points were shared.
The pair remain unbeaten in the league so far and occupy the top two places, with PSG trailing by two points.
