Rafael Benitez has admitted he is concerned by the lack of clarity surrounding Liverpool's travel plans ahead of Thursday's Europa League meeting with Atletico Madrid.
Benitez has praised club officials for the way they have handled the uncertainty caused by the cloud of volcanic dust which has closed down almost all air travel in Europe in the build-up to their semi-final first leg trip to Spain.
However, the Spaniard has suggested that UEFA should have considered postponing the game with his club involved in Premier League action on Monday night and Sunday afternoon.
Speaking after Monday's 3-0 Premier League victory over West Ham United, Benitez admitted the club were assessing their travel plans hour-by-hour.
Airport closures across Europe means the Reds may be forced to depart Liverpool on Tuesday morning for a marathon road and rail journey across the continent.
"In these special circumstances it could be better to postpone the game but we have to go," suggested Benitez, whose side are involved in league action at Burnley on Sunday.
"We had some time yesterday to rest the players. It will not be ideal but we will try to do the best for the players.
"The news we have is we will go to London and see what can happen. Maybe then the airports will be open and maybe we can fly from there.
"The key point is we can prepare the flight or travel to Madrid but we have to wait.
"We have the organisation for coming back as soon as possible but any way it will be Saturday – which is not the best for the Premier League game.
"If the airports are open maybe we can fly directly but at this moment it is more difficult to come back than it is to go.
"We are assessing things hour by hour. We have two or three options going and at this moment just one coming back but we will see if we can improve that."
