Watch Jack Grealish stick it to the haters with two goals on his full England U21 debut

He's back to his best.

Jack Grealish is settling into life as an England U21 with Gareth Southgate, and life in white seems to be suiting the former Ireland underage international quite well. https://twitter.com/England/status/734821871049400325 Grealish began life as an England international last week, when he came on as a second half substitute in an U20 tournament being held in France. The reaction to his debut was mixed, but tonight he silenced his critics, with two well taken goals as England spanked Guinea 7-1. His first strike was a nice effort, as he showed good control to slam home a cross. https://twitter.com/ONELOVEAVFC/status/734835097619288064 His second goal was a tidy effort from the edge of the box, as he passed the ball into the bottom corner. https://twitter.com/ONELOVEAVFC/status/734835796814012416 Grealish seems to have turned his critics into people who can appreciate his talent. https://twitter.com/ANNEMARIEsport/status/734834234012106752 https://twitter.com/phil_little/status/734833896941047809 But some people will never be convinced. https://twitter.com/apb_2009/status/734829563755253764 https://twitter.com/DecwaleWale/status/734836681103265793 The man himself was only delighted. https://twitter.com/JackGrealish1/status/734846615425581056
