French tennis player Gaël Monfils revealed Friday that he had received a barrage of racist abuse through social media after his second-round exit in the Italian Open.

In an Instagram post starting with the warning "watch your eyes" the world number nine shared a few of the abusive messages which made reference to his colour and called him a "loser".

Often Monfils, 35, responds to frequent abuse directed at him and his family with emojis of black hands.

"Unfortunately I gave it everything, but was very bad," he wrote above one insulting post after Thursday's match.

"Not a good evening, but I hope to come back stronger."

The French player made his return in Rome after more than six months off court due to the coronavirus pandemic. 

After receiving a first-round bye he was eliminated 6-2, 6-4 by German qualifier Dominik Koepfer, ranked 97th in the world. 

"It was really not great," said Monfils of his last warm-up before the French Open, where he reached the semi-finals in 2008.

"It frustrates me enormously to have played so badly."
