Lionel Messi is reportedly the Barcelona player to have been involved in a training ground argument with a teammate this week, with goalkeeper Marc-Andre Ter Stegen the other player.
Things at Barcelona aren't good right now and the Spanish champions have lost their spot at the top of La Liga, whilst also being knocked out of the Supercopa at the semi-final stage.
The club have replaced Ernesto Valverde as manager but earlier this week Messi 'slammed' sporting director Eric Abidal over the Frenchman's comments about the sacking of Valverde.
Also earlier this week there were reports that two players had been involved in a training ground spat and Spanish outlet El Pais is now reporting that it was between Messi and Ter Stegen.
Barcelona fans will be hoping that the training ground clash is nothing more than the usual thing that goes on between teammates, especially when tensions are running high.
The issues surrounding Messi have led to rumours that the six time Ballon d'Or winner could leave and he reportedly has an agreement with the club that allows him to leave on a free.
