Barcelona are considering flying to London for the Champions League final a day earlier because of the possible disruption caused by an Icelandic volcano, according to media reports on Monday.
Barca were planning to fly on Thursday in order to have two days in the English capital ahead of Saturday's final against Manchester United at Wembley, dpa reported.
However, the possibility that British airspace might be closed due to the ash cloud emitted by volcano Grimsvotn may cause the Spanish champions to bring their flight forward to Wednesday.
Barca will make a decision on Tuesday, in light of information issued by the European air traffic agency Eurocontrol.
Barca coach Pep Guardiola said on Monday that he was worried that some of the club's fans might not be able to fly to London for the final.
"The point of reaching the final," he said, "is so your fans can see you playing in it."
Guardiola pointed out that the Manchester United fans will have no problem in getting to Wembley "because they do not have to fly there."
Around 25,000 Barca fans are planning to make the trip, most of them by plane on Friday and Saturday.
In April 2010, during Europe's previous Icelandic volcanic ash crisis, Barca were unable to fly to Milan to face Inter in the semi-finals and instead had to make a two-day coach journey.
Guardiola's team looked tired after the trip and lost 3-1, a result which contributed to their not making the final.
