Ennis scored six goals in 46 appearances for Fleetwood Town in all competitions last season
Stockport County have signed Manchester United winger Ethan Ennis for an undisclosed fee on a three-year deal.
The 21-year-old scored three times in 39 League Two appearances on loan at Fleetwood last season.
He could make his debut for the Hatters against Blackpool on Saturday.
“Ethan was initially made available to us on a loan basis so to be able to turn that into a permanent deal feels like a real coup for the club,” Stockport’s head of recruitment Jonathan Smith told the club website.
