Sergio Busquets said on Monday he was still in a state of shock after Lionel Messi’s departure as Barcelona prepare to start their first Champions League without the Argentine since 2003. 

Barca face Bayern Munich at Camp Nou in Group E on Tuesday and will begin the competition as outsiders following a traumatic summer transfer window. Facing debts of more than a billion euros, the club let go 11 players, including Messi, who joined PSG after being told his contract could not be renewed.
