Barcelona officials are growing increasingly concerned by centre-back Gerard Pique's off-the-field antics, according to a report.

The Catalan giants let the 31-year-old off with a warning earlier this week after he was pulled over at a traffic stop and found to be driving without a valid licence.

Sport suggests that the Spanish champions fear their reputation is being hurt by Pique's behaviour, however, with the defender's love of poker, and various business ventures, adding to the growing tensions behind the scenes.

Asked about Pique's latest driving offence, Barca spokesman Josep Vives said: "It's part of a person's private life and he will have to resolve it himself. You can't punish him twice for the same thing."

Pique signed a new-long term deal with Barcelona in January that will run through until the summer of 2022.
