Barcelona will fly in to the UK two days ahead of schedule to avoid disruption caused by volcanic ash.
Josep Guardiola's first team will arrive in London this evening and begin preparations for Saturday's Champions League final against Man United at Wembley.
A cloud of ash being spewed by the Grimsvotn volcano has gradually been engulfing UK airspace, leading to the cancellation of many flights.
A spokesman for Barca admitted that it would be "complicated" for many of the club's fans to travel to the UK, adding: "For the moment we are keeping flight reservations and we plan to make alternative travel arrangements by coach."
