After appearing in a video where he jokingly slapped a member of the coaching staff last week, Ezequiel Lavezzi is at it again.
But the Paris Saint-Germain striker, a target for Chelsea, this time took it a step further.
With Manchester City striker Sergio Aguero struggling with a hamstring injury, Lavezzi was readied on the sideline.
But rather than go through the usual stretching routine, Lavezzi, while taking instruction from his manager Alejandro Sabella, squirted the boss with his bottle of water.
Sabella hardly seemed to notice - with his side well on their way to the knockout stages the manager probably didn't mind the light-hearted gesture.
Argentina went on to win a thrilling encounter against Nigeria 3-2, thanks to another wonderful performance from Lionel Messi.
The Barcelona scored twice for Argentina to top Group F.
