Kylian Mbappe was substituted in Paris Saint-Germain's win over Lyon as a precaution after he twisted his ankle, says boss Mauricio Pochettino. 

The France superstar scored twice in the 4-2 triumph to bring up 100 career Ligue 1 goals, but there was concern when he limped off to be replaced by the returning Neymar with 20 minutes remaining at the Groupama Stadium. 

However, speaking at a news conference after the game, head coach Pochettino moved to allay fears over the situation. 

"The Kylian Mbappe substitution was just a precaution. He had a knock, a twisted ankle," Pochettino said.

Danilo Pereira and Angel Di Maria were also on the scoresheet against PSG's title rivals, with Islam Slimani and Maxwel Cornet scoring consolations for Lyon. 

Pochettino's side are now back at the summit of the table after Lille lost to Nimes, and the Argentinian was particularly impressed with the conviction of his side, given Lyon had a week off while PSG defeated Lille in the Coupe de France on Wednesday. 

"I'm very happy with our performance, the truth is that we played very good football for 60 to 65 minutes against a very difficult opponent like Lyon," he added.  

"I'm happy, the players deserve all the credit because of the way they played. And we faced a very tough team who had all week to prepare against us, while we produced a great performance midweek against Lille. So, I want to congratulate my players for a good job. 

"It's very important to keep improving after two and a half months, I think we have played 19 or 20 games. Improving every day is the most important thing and playing at this level for 90 minutes is our aim.  

"We need to take what we showed for 60 minutes and do that for an entire game. With hard work we'll get there, it is true that there is no time, but we are at the beginning of our project and after two and a half months we are alive in three competitions, Ligue 1, the Coupe de France and the Champions League."
