UEFA have said they will discuss the huge travel chaos and the effect it could have on all European football this coming week in a specially convened meeting on Monday.
Most of Europe is under a total air travel black-out due to an erupting volcano in Iceland. The first major eruption of this volcano for 200 years, combined with wind directions, has brought air traffic to a complete stand-still.
Liverpool were due to fly out to the Spanish capital on Wednesday in preparation for their game on Thursday night, but with no sign of flights returning there is a strong chance that the game could be postponed. This could have a significant knock on effect for Liverpool – the 2nd leg was scheduled for the following Thursday.
