John Cofie and Gyliano van Velzen have returned to United following loan spells with Sheffield United and Royal Antwerp respectively.
Striker Cofie has been part of the Blades' first-team plans for much of their season as they aim to gain promotion to the Championship and recently spoke about hoping to see out the campaign in Sheffield.
The Ghana-born forward scored twice in eight starts for Danny Wilson's side and made eight further substitute appearances, including in the last outing against Doncaster Rovers.
However, he has headed back to Manchester and will be joined at Carrington by van Velzen (pictured). The Dutchman has been stationed at Royal Antwerp and scored his first senior goal whilst in Belgium.
