The official Scottish Sky Sports Twitter account broke the news on Saturday afternoon as the youngster, who hasn’t featured for the Red Devils so far this season, is set to leave the club in order to continue his development.

Blackett was thrust into first-team action at the start of last season due to a shortage of central defenders for United and made a total of 11 appearances in the Barclays Premier League.
His last competitive outing for the club came in the penultimate home game of the 2014-15 campaign against Arsenal and he inadvertently diverted a Theo Walcott effort into his own net and denied United all three points that day.
The 21-year-old is held in high regard at Old Trafford and signed a new with the club earlier in the year and a fruitful loan spell at Celtic Park could help him stake his claim for a regular place upon his return next summer.
