Arsenal are doing Barcelona a huge favour by allowing them to use their training ground.
Barcelona coach Pep Guardiola and his players flew to England last night because of fears about the ash cloud affecting air travel before the Champions League final on Saturday.
Arsenal have put aside recent rows surrounding "tapping up" storms over Cesc Fabregas to allow them to use London Colney on Wednesday night and Thursday before facing Manchester United.
Swansea City will also use Arsenal's Hertfordshire HQ on Sunday ahead of Monday's play-off final at Wembley. http://www.mirrorfootball.co.uk
