Arsenal star Mesut Ozil joined the party as Barcelona celebrated their Champions League Final triumph.
Barcelona beat Juventus 3-1 on Saturday night to win the trophy for a fifth time, with Ivan Rakitic, Luis Suarez and Neymar on the scoresheet.
German newspaper BILD reported that Arsenal's Mesut Ozil and Schalke's Julian Draxler joined the Barcelona team after the game at a nightclub, which was held in the country's capital, Berlin.
The paper report Ozil had a cost-free night, with his drinks paid for personally by Brazilian ace Neymar.
Ozil is in Germany preparing for an international friendly with USA on Wednesday, followed by a Euro 2016 qualifier against Gibraltar next Saturday.
The two-time FA Cup winner's drinks with the Barcelona side are seemingly innocuous, a chance to socialise with fellow top international stars, but it may not go down too well in the Spanish capital.
Ozil is a former star of Barcelona's bitter rivals Real Madrid, playing against them in several ill-tempered El Clasico's during Jose Mourinho's reign as manager.
