The 21-year-old striker only moved to Sunderland in January.

Alloa Athletic are set to sign Connor Shields on a season-long loan from Sunderland, according to the Scottish Sun.
But the newspaper claims Shields will continue to spend much of his time training with Sunderland, before linking up with Alloa ahead of matchdays.
It adds that a move for the striker – who is said to have had interest from other clubs north and south of the border, in Morton and Nuneaton respectively – should be concluded today [Thursday].
Shields only moved to Sunderland from Albion Rovers in January, and is still awaiting his debut for the Mackems’ first team.

The 21-year-old has however travelled with Jack Ross’s side to matches this season.
Shields scored or assisted 15 goals in 20 Scottish League One outings during the first half of last season, three of which arrived in a 5-2 win against Alloa, who later won promotion to the Championship, in September.
Sunderland will be able to recall Shields during the January transfer window, according to the Sun.
