7) Jack Grealish (Aston Villa)
Teenage winger Jack Grealish has played a central role in Aston Villa’s pre-season preparations, after making his debut for the club against Manchester City at the end of last season.
Grealish had spent the majority of the 2013/14 campaign on loan at Notts County, where his quick footwork made him one of the most dangerous players in League One.
