Manchester United reporterPublished12 minutes agoManchester United youngster JJ Gabriel has travelled to Barcelona as some of Europe's biggest clubs continue to vie for his signature.
The 15-year-old has told United he wants to cancel his registration with immediate effect.
BBC Sport reported on Thursday that Real Madrid have a firm interest in the forward, and Bayern Munich, Paris St-Germain and Barcelona are also known to be keen.
It is understood Gabriel left the UK on Thursday and went to France, but is now in Barcelona.
If United hold on to the Londoner's registration, it would stop him moving to another English club until the end of the season.
But if he obtains an European Union passport through either his father - a former Republic of Ireland international - or mother, who has Greek-Cypriot heritage, he could join a club in he EU when he turns 16 on 6 October.
Sources close to Gabriel were furious the club did not register him for their Champions League opener with Sabah FK, which Michael Carrick's side won 4-0.
Carrick was again asked about Gabriel on Friday at his news conference to preview Sunday's Premier League match against Fulham.
"He's a young boy, JJ, and I think it's important we don't play anything out here," he said.
"With the exposure and scrutiny and everything, you got to be careful and be sensible and think of him as much as anything.
"The situation will work itself out, whatever way it's going to work itself out. Making sure he's OK is the important thing."
Gabriel scored in his first two Premier League 2 outings for United this season but will not be involved against Brentford at Leigh Sports Village on Friday.
