Barcelona coach Pep Guardiola says the Liga's referees need to end their inconsistencies.

Guardiola believes there's too much "suspicion" around decisions at the moment.

He said: "It's been a while now that the committees haven't demanded respect. We're at a point where everything is too suspicious. There are too many things that they've let pass, and in the end they haven't made themselves respected. Gerard [Piqué], with what he said, probably deserved a ban.

"But they don't do it, of course, because if there's another player that says that his team was robbed, they'd have to ban him too. This has been going on for a while, and they [the committees] urgently need to reestablish respect."
