ShareEndrick made a flying start to life at Lyon, but the Real Madrid loanee has been unable to build on that momentum in recent weeks.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."
