The Argentinean coach was involved in a couple of touchline arguments: first, against Bayern's bench, and when the game came to a close, he was frustrated by the officer's slowliness to show the board.

Diego Simeone is known for his flamboyant and intense style of coaching, but this time he might have crossed the line.

During the second leg of the semi-final clash against Bayern Munich, Simeone's touchline antics were the cause of controversy. First off, he got involved in an argument with Die Roten's bench, forcing Franck Ribery to get a grip on the Argentinean before things escalated. Reports from Spanish sources claim he told one of Guardiola's assistants "Go f**k yourself".

But later, when the game was entering stoppage time, Simeone's temper exploded. As Atlético tried to stall, Atlético's UEFA delegate Pedro Pablo Matesanz wasn't quick enough to show the board announcing a substitution for los Colchoneros. Infuriated, Simeone slapped him with his right hand.
