Kylian Mbappe is pleased Paris Saint-Germain are involved in a title race this season as it demonstrates just how hard it is to be crowned Ligue 1 champions.

PSG closed to within a point of leaders Lille thanks to a dramatic 3-2 triumph over Saint-Etienne on Sunday, Mauro Icardi grabbing the winner deep into stoppage time at the Parc des Princes.

Mbappe underlined his importance by scoring twice in the see-saw contest, cancelling out Denis Bouanga's opener with his first before putting the hosts ahead from the penalty spot.

However, it seemed Saint-Etienne had secured a point when Romain Hamouma made it 2-2 in the second added minute.

"We got into a bit of trouble. When we lead 2-1 like that, we have to keep the score," Mbappe told Canal+. "But we didn't give up, we wanted to win.

"The championship is extremely important to us - it is a primary objective. It would be the 10th for the club and we want to participate in the history of the club.

"We want to win, we are competitors. People think it's easy to win. This year, it's good, there is a title race, it shows that it is not easy what we have done in recent years.

"We want to keep doing it. There is no secret; we have to give our all and win all the matches."

Only Zlatan Ibrahimovic and Edinson Cavani have scored more goals in Ligue 1 for PSG than Mbappe. He has 23 in 28 appearances in the competition this season, as well as a further eight in the Champions League to help his side reach the semi-final stage.

Mauricio Pochettino is optimistic over the 22-year-old signing a new deal to extend his stay in the French capital, too.

"I am an optimist, and I hope that the best players at the club, in this case Kylian, will stay here," the PSG coach said.

On the game itself, Pochettino was pleased with the character shown by his players, particularly after they had seemingly let the win slip away when Hamouma equalised for the visitors.

"I don't know if it's a champion's victory, but it's the victory of a team which believes in itself, which does not surrender," Pochettino told the media.

"These are three very important points to stay in the championship race until the end. As staff, we always advocate confidence, optimism. This attitude is very important for approaching life and football.

"The team has the mentality, not just athleticism and talent, but also character. These three points give us energy, a very positive feeling to face what awaits us and which will be difficult."
