The 20-year-old is one of Manchester United's brightest prospects, but will be given the chance to get plenty of football under his belt this season away from Old Trafford.
The 20-year-old has been in and out of the Red Devils' first team since Louis van Gaal took over at Old Trafford, having enjoyed a strong breakthrough campaign during David Moyes' spell in charge, though he has already made 4 appearances this season, scoring the winner in the match away to Aston Villa.
Sky state that Januzaj is in advanced talks with Borussia Dortmund over a move, but until things are done and dusted, there is a chance he could instead choose to boost his Premier League experience ahead of a return to United.
Though the Belgian international is a quality player capable of becoming one of the top talents in European football if he fulfils his potential, the benefits of a move to either Spurs of Everton wouldn't necessarily lie with either club that would receive Januzaj on loan, instead helping United develop someone they would have little chance of signing in a year's time.
The Londoners and the Merseyside club both have their own share of promising attacking talent that can feature out wide and in the number ten role, and although Januzaj could perhaps be an improvement for either team when it comes to squad depth, the danger would be that his arrival would inhibit the development of those that are already at the club.
For the Toffees, Ross Barkley has started the season in strong form, while Gerard Deulofeu is still yet to come into the team.
At White Hart Lane, where two more wingers have just been signed in Clinton N'Jie and Heung-min Son, Alex Pritchard deserves a chance deputising for Christian Eriksen in the middle of the park, while a big name striker signing could see Harry Kane drop deeper.
Januzaj's arrival at Spurs in particular would be peculiar, with up front and defensive midfield remaining the obvious positions that need strengthening.
