Diarra only spent a year at PSG, announcing his retirement when his contract was terminated by mutual consent in February 2019.

The Le Havre academy product played for Chelsea, Arsenal and Portsmouth before heading to Real Madrid in 2009.

After some time in Russia with Anzhi Makhachkala and Lokomotiv Moscow, Diarra went to Marseille for 18 months and joined Al Jazira in the United Arab Emirates upon his release, prior to joining PSG.

Mbappe valued Diarra's advice and also the presence of FIFA World Cup winner Buffon, who played for PSG in the 2018-2019 season before heading back to Juventus on a free transfer.

"He was Uncle Lass, a big brother you could count on," Mbappe told L'Equipe. "He often told me about his career, his clubs. He made mistakes, so he advised me.

"He helped me during complicated times. The high level – he knows what he is talking about. He went to a lot of clubs all over the place. He left home very early, and alone. I always liked listening to the elders. Buffon was also very important to me.

"But Lass wasn't just talking to me. He also spent a lot of time with Presnel Kimpembe. And he always played this role even when he was not playing. That is very important.

"Lassana was highly respected in the dressing room. It did something to me to see him go. It also did something to me to see Buffon go."

PSG was declared Ligue 1 champion when the season was curtailed in April because of the coronavirus pandemic.

It will return to action in the UEFA Champions League quarter-finals in August.
