Yeah Pique is more likeable then the reverse, as most clownish types are.
He used to be more annoying in Sevilla, because he was really ill tempered and HUGE diver, he is still bit of a loose cannon, and still dives, but not as full time every single game antics as he used to be in Sevilla (was the star all attention was on, ran their attack), more mellow/quiet in Barca. But yeah, he is bit similar to Melo in attitude, not as violent, but defenitely a cuckoo guy.
