Arjen Robben used to be notorious for being a petulant player, and the Dutchman was up to his old tricks for Bayern Munich again last night.

He was directed to take a penalty for the Champions League holders in their crushing win over Viktoria Plzen, when he was fouled in the 25th minute.

“Arjen, Arjen”, Bayern Boss Pep Guardiola yelled from the touchline, as the players discussed who should take the spot kick.

But Robben was bitter after Guardiola chose Thomas Muller to take a penalty instead of him during Bayern’s Bundesliga win over Mainz last weekend.

And so visibly irritated, he blew a raspberry at Pep, and refused to take the penalty.

Guardiola admitted after the game that Robben had ignored his instruction, but the player did not want to be drawn on his minor misbehaviour.

"I do not want to talk about it," he hissed.

"Let's not talk about it, let's drop it.

"We had a very good game and 5-0 is a great result but we could have done better if we really want to be very critical."

Robben’s wing accomplice, Franck Ribery, who ultimately scored from the contentious penalty and enjoyed another generally blistering game, was left explain the situation.

"Arjen was a bit irritated," he said.

"The coach said Arjen but Arjen did not want to shoot.

"That is football. it can happen it's natural.”
