Carlos Bacca glared at Milan Coach Cristian Brocchi after a substitution against Carpi, then stormed out of the stadium.
The Colombian striker was visibly angry when he was hauled off to make way for Jeremy Menez during the 0-0 draw with Carpi this evening.
He walked straight down the tunnel without saluting Menez, going past the bench and glaring at Brocchi.
According to Mediaset Premium, Bacca then got in his car and drove off from San Siro without waiting for his teammates to finish the match.
