Chelsea and Arsenal will both hope to be in the draw for the Europa League quarter-finals.
The Blues are 3-0 up against Dynamo Kiev on aggregate after the first leg of their last 16 tie.
Arsenal have more work to do after suffering a 3-1 loss to Rennes following a Sokratis red card in the first game.
Chelsea could indeed face Arsenal as there is no country protection from the quarter-final onwards.
