Manchester United's young attacking midfielder posted the above image onto his Instagram account earlier today along with the caption, "Back in training with @felli31".
The pair have joined up with new boss Louis van Gaal and the squad in Washington DC, where the club are currently training as part of their pre-season tour of the USA.
Fellaini has seemingly reverted back to his old afro hairstyle, after sending shockwaves throughout football earlier this month when an image emerged on Twitter of him sporting a much shorter haircut.
However it turned out that the £27million midfielder had only had his 'fro tied down with temporary braids.
His future is far from certain at United as van Gaal looks to stamp his own mark on United's squad. Fellaini failed to have any real impact during his debut season in Manchester, and reports claim he could soon be sold off.
Januzaj on the other hand will be hoping van Gaal will enable him to build on the fantastic breakthrough season that he had under David Moyes.
Tying the 19-year-old into a long-term deal at Old Trafford was arguably the best piece of business Moyes did, and Januzaj went on to make 35 appearances and score four goals in all competitions.
