Robert Lewandowski was the man of the match as Barcelona defeated Real Sociedad 4-1.
After the final whistle of the game, Lewandowski went to greet the match officials, and referee Munuera Montero told Robert Lewandowski a funny joke.
As they shook hands after the game, Montera told the Barcelona striker: “Good luck. Watch out with your watch!”
Both laughed after that.
Meanwhile, Xavi also lavished praise on the Poland international who celebrated his 34th birthday with a brace.
He said: “Everyone has seen that Lewandowski can make a difference. He’s an example for the team because of the sacrifices he has made. He is a player for the present and the future.”
