The Catalan giants were in high spirits again on their third day of their pre-season preparations in England having arrived at Birmingham Airport on Monday morning.

Barcelona's five-day stay at the FA's £105million facility ends on Saturday morning when they'll head to Aviva Stadium for a 6pm kick-off.

Martin Montoya was the only player in camp to sit out training, suffering a minor hamstring problem, before the players were given the rest of the day off.
