Former PSG coach Unai Emery says Kylian Mbappe needs to keep his ego in check.

The France World Cup winner has clashed with teammates and coach Thomas Tuchel this season.

Former Arsenal manager Emery, who convinced Mbappe to resist Real Madrid and join PSG from AS Monaco, told France Football: “It's a story of ego.

"Kylian, I know him, he's a good guy. But he is ambitious. However, this ego which emerges and which he displays publicly against the trainer, it is not good for his image and that means that he does not control his emotions.

"But, basically, it means that he is a player who wants more, that he is a winner. I would always prefer a disgruntled player against me because he does not play, because that means that he is a competitor."
