Romain Hamouma's header has pulled Saint-Etienne level at 1-1 with Paris Saint-Germain at half time in the semi-final of the Coupe de France, after Zlatan Ibrahimovic's penalty had originally given the hosts the lead.
The home side started in an eager fashion as Zlatan Ibrahimovic whipped in the perfect ball for Ezequiel Lavezzi, who saw his header stopped by Stephane Ruffier in the Etienne goal.
Laurent Blanc's men were given the perfect chance to take the lead when Lavezzi was brought down inside the box, leaving Ibrahimovic to lash home from the spot to make it 1-0.
The lead was not to last too long, however, as Etienne striker Hamouma gambled well inside the PSG area to head beyond a helpless Nicolas Douchez in the 25th minute.
The visitors should have pushed ahead five minutes later when Gregory van der Wiel handed a gift to Mevlut Erding, but he somehow shot wide of the target with Douchez seemingly stranded.
The Parisians almost made them pay for their profligacy just before the break when Javier Pastore showed some neat skill to find Ibrahimovic, who was put under just enough pressure to make his chance go begging.
