Paris St-Germain boss Mauricio Pochettino has revealed an injury was the reason he substituted Lionel Messi during Sunday’s win over Lyon.

Messi appeared unhappy while being replaced, but Pochettino said he had taken a knock to his left knee.

The 34-year-old will miss PSG’s trip to Metz on Wednesday and is a doubt for next week’s Champions League game against Manchester City.

Pochettino said he noticed “Leo was looking at his knee”.

“We are pleased with the way he played,” said the former Tottenham manager, who did not mention Messi’s injury following the game on Sunday.

“He played very well in the first half, and the only thing missing was a goal. He played for 76 minutes and, with all the information we had, we decided to take him off.

“Of course I understand the situation and I accept it as it is.”

The 2-1 win over Lyon was Messi’s third appearance for PSG since joining as a free agent after leaving Barcelona – and his first at the Parc des Princes.
