Januzaj, 20, burst onto the scene last season under David Moyes, scoring twice on his debut in a 2-1 win at Sunderland, and he went on to enjoy a number of fine performances, with many fans and pundits labelling the Belgian international as the next big thing.
Yet this season, Januzaj has found it much harder to make an impact. Moyes has of course left Old Trafford, and in his place as come Louis van Gaal - who has handed the young winger just seven Premier League starts this season.
Once full of skill, dribbling ability and a certain arrogance in possession, Januzaj now looks bereft of confidence, and with no goals or assists to his name this season, it's clear that something isn't right for the former Anderlecht prodigy at Old Trafford.
A loan move away from United may be beneficial for Januzaj, but the Manchester Evening News believe that van Gaal would be willing to sell if a bid in excess of £20m were to arrive.
They also note that Premier League rivals Everton are interested, along with Moyes' Real Sociedad, though it's unlikely to see either of those teams submitting bids of £20m or higher.
It's something of a fall from grace for Januzaj, who was earning plaudits left, right and centre this time a year ago - but now he must prove himself, either at United or elsewhere, with a place in Belgium's Euro 2016 squad on the line.
