VIDEO: Lonely Adnan Januzaj warms up with ball boy

It's safe to say Adnan Januzaj hasn't had much of an impact in his loan spell at Borussia Dortmund, and certainly less of an impact than Louis van Gaal - the manager of his parent club Manchester United - hoped for.

Maybe it's because he's struggled to make friends.

The young Belgian was named on the bench for the Bundesliga side's disappointing 1-0 loss to Krasnodar in the Europa League on Thursday, which isn't surprising given he's managed just two competitive starts this term.

While his fellow substitutes warmed up together, the winger, looking like a "Billy no mates," instead went through his workout with a ball boy.

Januzaj already wrote himself out of a few Christmas card lists this year, with his refusal to join up with the Belgium Under-21 squad earlier this month.
