Paris Saint-Germain head coach Luis Enrique was pleased with his side's 3-0 win away to RB Salzburg in the Champions League on Tuesday, but still thinks they need to improve if they are to avoid elimination.

The French champions had not won a match in the competition since a 1-0 victory at home to Girona on Matchday 1, meaning they had slipped outside the play-off positions prior to their most recent victory.

While Tuesday's win lifted them into the final play-off place ahead of Wednesday's games, they still have Manchester City and Stuttgart to face in the new year.

With Paris Saint-Germain having accrued seven points from their opening six matches, Enrique believes things need to get better to get into the knockout rounds.

"Football is a pretty unfair sport, the classification is quite tight, a goal can make a difference and we still have two important games ahead, we can still be out," he said.

"This wasn't a better game than PSV or Atletico Madrid, I'd even say it was worse, but that's football. 

"We know we have to improve and the squad hasn't changed a lot. We need points, and we will try to win the next games."

Despite lobbying for improvements from his squad, Enrique did make time to recognise the performance of Nuno Mendes in Salzburg after the defender scored the second goal.

"Nuno brings other solutions for his physical and technical qualities. He can both complete the triangle at the back and play up front. He's playing higher up at the moment. He brings a lot offensively. But that could change," he said.
