This moment from a particularly feisty 2003 El Clasico suggests the next Barcelona v Real Madrid clash could get seriously heated <br /> <br />The biggest club game in world football is often so feisty, a potentially brilliant match between some of the planet’s most gifted players often descends into a petty, Sunday League style scrap. <br /> <br />Well, be warned people. Because, in the words of Danny Dyer, Real Madrid v Barcelona is about to get “proper naughty”. Watch the video above and you will see why. <br /> <br />The clip comes from the 1-1 draw at the Bernabeu in April 2003, and shows a melee provoked by a fight between either side’s key midfielder. Yes, it’s Real Madrid manager Zinedine Zidane – who has just replaced Rafa Benitez in football’s hottest hotseat – in a head-to-head with current Barcelona boss Luis Enrique. <br /> <br />Well, we say head-to-head. It’s more like hand-to-face. <br /> <br />Doesn’t suggest the two men now in charge of Spain’s biggest clubs are particularly fond of one another, does it? <br /> <br />For those of you into forward planning, the next edition of football’s greatest soap opera takes place on 3 April 2016, at the Nou Camp. <br /> <br />Don’t about you lot, but we might spend more time looking at the touchline than the pitch. If things get particularly heated, we might even see the great Zizou replicate this.
