As of this moment, it seems unlikely that Manchester United will make any signings in January, with most of the club's transfer movement involving players leaving Old Trafford on loan.
MEN Sport understands that the majority of the club's business will be done next summer, with up to four signings targeted by United including a midfielder, a right-back, a forward and possibly a backup goalkeeper.
Though this may change upon the appointment of a new manager, it does seem to address all of United's major problem areas.
