The draw for the last 16 of the Champions League takes place in Nyon on Thursday, December 20 from 10.30am (UK time).
As runners-up in Group B, Arsenal will face a group winner in the first knockout round and will play the first leg at Emirates Stadium.
They cannot be drawn against the winners of their own section - Schalke - or a club from the same association, ruling out Manchester United.
That leaves Paris St-Germain, Malaga, Borussia Dortmund, Juventus, Bayern Munich and Barcelona as potential opponents.
