Lyon boss Paulo Fonseca has issued a rallying cry to Endrick, saying he is "not satisfied" with the on-loan Real Madrid forward.

The 19-year-old joined the Ligue 1 side on a six-month loan deal in January, as he sought regular first-team football in a bid to make Brazil's World Cup squad.

Endrick made a flying start with four goals in his first three games, becoming the club's youngest scorer of a hat-trick during a 5-2 win over Metz.

However, the Selecao forward has only found the net three times in his last six appearances, with his fading form coinciding with Lyon's nine-match winless streak.

"I am not satisfied with how Endrick is playing," Fonseca told reporters on Friday.

"I'm not here to break players, but I expect more from a player like Endrick, and I think he has the obligation to do more."

That comment came after Endrick produced a poor performance during Lyon's goalless draw with Angers last time out.

However, just days earlier, he had starred from the bench in Brazil's 3-1 win over Croatia in Orlando, winning a penalty and assisting the third goal for Gabriel Martinelli.

"He said he was a bit tired from the journey," Fonseca said. "But I think he has the responsibility to do more."
