Barcelona's key first-team players - including Lionel Messi, Luis Suarez and Neymar - have been given a three-day break after their exertions in the last-gasp win at Valencia on Sunday (AEDT).

Barca is not in first-team action this week, although a squad of fringe players and B team regulars has been named for Wednesday's (AEDT) Catalunya Supercup clash with Espanyol.

Luis Enrique has decided to give his key players a well-deserved break with Messi, Suarez and Neymar not expected back in training until the end of the week, alongside Marc-Andre ter Stegen, Ivan Rakitic, Sergio Busquets, Javier Mascherano, Lucas Digne, Sergi Roberto and Samuel Umtiti.

Nine of the 10 started the 3-2 victory at Mestalla - Rakitic came on as a 14th-minute substitute for the injured Andres Iniesta - and played a part in the comeback that saw the defending LaLiga champions snatch an injury-time triumph thanks to a Messi spot-kick.

Arda Turan has been included in the group to face Espanyol after overcoming an elbow injury but Aleix Vidal misses out after damaging his right adductor in training on Tuesday (AEDT).

Barca's next LaLiga game is on Sunday (AEDT) when Granada visits Camp Nou.
