The big-spending club suffered another frustrating evening as they followed up last weekend's stalemate in Ajaccio with another at the Parc des Princes
Opportunities were at a premium over the course of the match, with Zlatan Ibrahimovic providing much of the inspiration for the hosts. The visitors, meanwhile, offered menace on the break but were rarely allowed to trouble the home goal.
Bordeaux travelled to the capital with the aim of stifling their opponents and, for much of the first period, their five-man defence was unmoved against an attack that was often too static and too disjointed.
Ibrahimovic was a threatening presence at the head of the home side’s attack, hinting at his class after only five minutes when he clipped an effort just too high.
PSG struggled to get in behind the visiting defence, but on the one occasion they really achieved this, Javier Pastore had an effort brilliantly turned over by Cedric Carrasso.
There was a flourish from the hosts just before the break, with Nene having a fierce drive from range pushed wide and then Alex heading narrowly wide from the resultant corner.
If Francis Gillot’s side were content to play a containing game in the first half, there could be little doubt that they were somewhat more expansive after the break as their confidence steadily grew. Landry Nguemo fizzed an effort wide of Salvatore Sirigu’s goal, but their big opportunity came when Ludovic Obraniak and Mariano combined down the right to set up Cheikh Diabate. Despite a good first touch, though, he was denied by a fine block from Mamadou Sakho.
Despite more positive intentions from the Garonne side, though, they did start to be pinned back in the final quarter of the game. Ibrahimovic, who had fired a terrific free kick just past in the opening moments of the half, nearly proved to be the matchwinner with a fine turn-and-shot following a corner.
Although for a period the passing of the home side became sharper and more intricate, they largely lacked incision in the final third. Substitute Jeremy Menez did offer some promise, but his best efforts inevitably flew straight into the midriff of Carrasso, who has now gone 11 career games without losing against PSG.
With only three points from their first three matches, the pressure will now start to mount on Ancelotti, particularly ahead of a trip to Lille next weekend that will be anything but simple.
