Barcelona duo Alex Song and Gerard Pique appeared to get caught up in a scrap during the club's open-top bus parade to celebrate their La Liga-winning campaign.
The pair were snapped by cameras grappling on top of the bus as they drove through the Catalan city celebrating their triumph with supporters lining the streets.
The duo could have been play-fighting, but photos published by the Daily Mail show Song pulling back his arm ready to punch Pique, who crouches down with his hands up to defend himself.
From the images, it appears that Carles Puyol and Victor Valdes calmed the situation.
