Chelsea have been drawn with Sparta Prague while Tottenham will meet Lyon in the last 32 of the Europa League.
Arsenal have been drawn against last season's losing finalists Bayern Munich in the last 16 of the Champions League.
Arsenal will find out their opponents for the last 16 of the Champions League knockout stage when the draw is made in Switzerland this morning. The Gunners are not one of the top 8 seeds which means they will be drawn against one of the group winners from the last stage.
Their potential opponents are Paris St-Germain, Malaga, Borussia Dortmund, Juventus, Bayern Munich or the tournament favourites Barcelona.
Chelsea and Tottenham will also discover their opponents for the last 32 of the Europa League. Amongst the big names in the draw are Benfica, Inter Milan and Lazio.
