Barcelona coach Pep Guardiola has hit out at teams which keep their grass long when the champions come to visit.

Guardiola claims only Athletic Bilbao cut their pitch's grass for Barca visits.

"At every field away from home it is always true. In the Bernabeu (Real Madrid) and also everywhere else they leave it high, except for Bielsa's Athletic.

"It is their right, but I am not impressed."
