It's safe to say that Atletico Madrid boss Diego Simeone is one of the most unpredictable managers in the game.
The Argentine, who masterminded his side's progression to the Champions League final on Tuesday night, is an incredible character who continues to surprise his followers.
Indeed, Simeone's success at Spanish outfit has been truly remarkable and him and his side are showing no signs of slowing down.

Back in 2014, the enigmatic coach led Atletico to the La Liga title, while he was also extremely close to securing the Champions League trophy.
But in their last European final, Simeone and co. were left heartbroken as rivals Real Madrid secured the prestigious prize with a dramatic victory in extra time.
There's every chance, however, that Simeone will lead his side to the trophy this season. They may well have a shot at redemption against Real Madrid or come up against Premier League outfit Manchester City.
Whoever they face, it's safe to say that Atletico won't be worried. That's because they have Simeone and he oozes confidence.
He is most definitely brilliant, but he is also mad. He proved that notion once again on Tuesday night as he pushed the fourth official and attempted to have a scrap with Bayern boss Pep Guardiola.
Simeone has only just been handed a touchline ban in La Liga, of course, after appearing to instruct a ball boy to halt the attack of the opposition.
11-year-old ball boy
But it appears that he has always been a little mad...
And how do we know that? Well, as reported by the Daily Mail, Simeone was once sent off as an 11-year-old ball boy. Of course he was...
It was back in 1982 for Velez Sarsfield against Boca Juniors when a young Simeone threw an extra ball onto the field of play to help his team start a quick attack.
Apparently, according to the man himself, one ball had been thrown off by the 'keeper but bounced back on off the advertising board. We're not quite sure if we believe him.
Love or hate him, it's hard not to respect. What he has achieved at Atletico is truly brilliant and there could be no stopping him and his side in the pursuit of success.
His side may not be the most attractive on the planet, but they are certainly difficult to beat and could become European champions sooner rather than later.
