The fullback has been linked with PSG.
"Itâ€™s very hard to get the chance to play for Barcelona and, whether people like it or not, Iâ€™m part of the history of this club," he told RAC1. "I need energy, itâ€™s what motivates me; Iâ€™m an upbeat, happy person.
"Iâ€™ve always been like that, but because the results arenâ€™t what people expect, they need someone to shoot at and I feel shot at. I really believe in energy, I live off this energy and, if you start to create negative energy, things donâ€™t flow.
"If this energy doesnâ€™t change, Iâ€™ll probably leave because it wears you down. If I'm to stay this summer, there has to be a change of energy."
