The United player's inclusion has ultimately acted as the hammer blow to the hopes of PSV winger, and Liverpool target, Zakaria Bakkali.
Despite making his debut for Belgium earlier in the season, the 18-year-old has missed out on the final roll call and now faces a future of battling the United winger for a first-team place in the Belgium national team.
The inevitable competition with Januzaj is likely to shape the player's international career and because the United winger plays in a better documented league, it may be difficult for the Dutch-based player to oust him from the side. And this is where we feel Liverpool could come into play.
It is no secret that the Premier League is the most watched and talked about division in the world. On average, Premier League football pulled in an average attendance of 34,601 last season - a figure that can only be beaten by the Bundesliga.
In comparison with Eredivisie's underwhelming average of less than 20,000 a match, it shows dominance.
Nevertheless, it's not only the huge number of fans it brings through the gates that makes the Premier League so attractive as the figures from last season showed.
The Premier League attracted a television audience of 4.7 billion people overall last season, a number that can't be touched from any other league in world football.
It would provide a perfect stage for Bakkali to compete with Januzaj on a weekly basis, and ultimately be seen around the world for the great player he is.
The Reds have been the most prominent Premier League name to be linked to the highly-rated PSV star, and after missing out on the World Cup it may mean the stars could align for Brendan Rodgers this summer.
Arsenal are also said to be interested, however, as things stand, Liverpool are arguably the more attractive proposition and could sign the player if they wished.
As for Bakkali as a player, it certainly didn't take him long to burst on the scene in Eredivisie and soon earned a name for himself after netting an incredible hat-trick on his league debut.
The teenage wonder showed his intelligence, awareness, pace, power and trickery in his debut match, pulling a stunned NEC Nijmegen apart. There was no doubts his third and final goal that game was his best, showing confidence to beat his man and curl the ball into the top corner from around 18-yards.
