The Three Lions convinced the 20-year-old to pick them over the Republic of Ireland, but must now wait around a month for international clearance from Fifa.
Monday was an important day in the life of Aston Villa star Jack Grealish, as he announced the country he wished to represent in international football, something that could very much go on to define him as a footballer. But despite his decision, England boss Roy Hodgson can not yet call the skilful youngster up to his Three Lions squad, according to the Mirror.
Grealish had been at the centre of a tug of war between the Republic of Ireland, who he had represented throughout youth football all the way up to the Under-21s and who he was tied to through his grandparents, and England, the country of his birth and where he'd lived his entire life.
The attacking midfielder is one of the most promising talents to have come from the British Isles in the last couple of years, and whichever country he would have ended up choosing, it is likely Grealish will emerge as an international star in the next couple of years.
But now he has chosen to declare for England, Roy Hodgson must decide how best to use the 20-year-old.
The Mirror says England must apply for and wait for international clearance before he can feature for the senior side, a process that could take as long as a month, ruling him out of the final two European Championship qualifiers against Estonia and Lithuania, which Hodgson is due to name the squad for on Thursday.
Instead, a friendly fixture with Spain in November may be a more realistic prospect, though of course Grealish wouldn't be tied to a nation until he played a competitive match for any country, and it remains to be seen whether Hodgson will instead look to involve the Villa star with Gareth Southgate's Under-21 side.
Grealish will hope to gatecrash the England squad ahead of next summer's Euro 2016 tournament, with Hodgson's side having already qualified.
