Barcelona midfielder Xavi admitted on Tuesday that the club\'s players fear coach Pep Guardiola will decide not to renew his contract with the European champions. \"We\'re not ready to have a \'no\' from Guardiola. We\'re hoping he\'ll stay,\" said the Spanish international. \"Guardiola is a key element in the Barca system. I see him satisfied, enjoying himself. He continues to be as competitive as ever but the decision in the end is his. Personally, I think he will renew his contract.\" Uncertainty continues to surround the future of Guardiola, who is out of contract in the summer and has not yet committed to a new deal after a glittering three and a half years in charge at Camp Nou. Barca star Lionel Messi insisted on Monday that Guardiola was \"more important\" to the Catalan club than him, a day after taking his tally for the season to 50 goals.
