Brandon Williams has been promoted at Manchester United.
United have added Williams, 19, to their Europa League B list along with fellow teenagers Angel Gomes, Tahith Chong, James Garner and Mason Greenwood.
Left-back Williams did not train with the United first-team squad during their open session at Carrington on Wednesday, but has been in superb form for the Under-23s and did not figure in the Under-19s' friendly draw with Hertha Berlin at Altrincham on Wednesday evening, says the Manchester Evening News.
Full-back Diogo Dalot is in contention for his first appearance of the campaign against Astana but Luke Shaw is still injured and Solskjaer may rest Aaron Wan-Bissaka and Ashley Young.
