Mauricio Pochettino was satisfied with the effort put in by his Paris Saint-Germain team against Saint-Etienne, but said his players, including Kylian Mbappe, need to up their game.

PSG labored to a 1-1 draw in Pochettino's opening game in charge, with the former Tottenham boss having replaced Thomas Tuchel.

The Ligue 1 champions moved up to second thanks to Lille's defeat to Angers, but are three points behind leaders Lyon.

Saint-Etienne capitalized on Idrissa Gueye's mistake to take the lead, but Moise Kean's eighth league goal of the season cancelled out Romain Hamouma's opener.

Denis Bouanga hit the crossbar for Saint-Etienne after the break, while Kean snatched at a good chance and Angel Di Maria forced Jessy Moulin into action with what was PSG's only shot on target in the second half as the spoils were shared on Wednesday.

"I am happy with [Mbappe's] performance, of course he needs to improve, and of course he wants to score and wants to play better and win games," Pochettino told reporters after the game.

"For sure he is disappointed. I'm happy with Marco [Verratti], like Kylian, but all the players need to improve, the team needs to improve.

"It is only the beginning, we arrived three days ago.

"I am disappointed, because we are PSG and we want to win. But we didn't have a lot of time to prepare for the match.

"We still have a lot of things to improve, to develop. This is not the result that we wanted."
