Bring a spitfire into a crater of Mount Vesuvius? What could possibly go wrong...

What's the same thing you can say about both relationships and football? The opposites attract, and those contraries sometimes make an ideal connection.

Like yin and yang.

And what about yang and yang when a burning flame is complemented with a flamethrower?

Well, that's the exact story of the Italian side Napoli and their - according to Corriere Dello Sport - new head coach Sergio Conceicao. With Gennaro Gattuso, it seemed like a match made in heaven at some point, but the ill-fated finish of the season saw Napoli missing the Champions League in the last seconds of the ultimate Serie A round. And it was the end of the road for the edgy Gattuso in Southern Italy.

One would expect that an extravagant owner and film producer Aurelio De Laurentiis would now pick differently and choose some cold-blooded, slow-paced tactician to replace The Tasmanian Devil. But it's not De Laurentiis' style. There's nothing he likes so much like coaches of his own ilk - ready to burst into a fight for one questionable referee's decision.

So he did it again.

Sergio Conceicao is - in terms of coaching CV and qualities - a top drawer name in the business. Two Portuguese championships, several outstanding UCL campaigns with FC Porto, lots of praise coming from players, just to name a few. Those are virtues, with only one flaw on the other side. One, but utterly significant. Conceicao is as spitfire as it gets. Let's go for a ride...

In March 2006, reaching the autumn of his playing career, he was banned for three years in Belgium for spitting on an opposing player and assaulting a referee.

On 1 January 2012, he started his coaching career in Olhanense in Portugal but left the club after only seven months following disputes with the board.

In 2014, following a defeat of his new team SC Braga, president Antonio Salvador released an official statement that angered Conceicao, resulting in a "violent discussion" between the two and leading to the club's decision of sacking the latter.

And those were just a few of his short-fused episodes. He's been like that throughout his entire playing career too. So what's the catch? Why De Laurentiis thinks it would be different this time?

Maybe he sees something that we can not. Maybe in the outskirts of Mount Vesuvius - where two gods exist since the late '80s, the God itself and Diego Armando Maradona - it has to be different.

Maybe yang needs yang.

One thing is for sure - it won't be dull in Naples.
