2010

: UFWC: ? WC: ? Unification. Whoever wins on Sunday, they will become undisputed champions as holders of both the unofficial and official titles. No team has ever taken the UFWC title into a World Cup tournament and left with it at the end. Only one team has ever taken the title into a World Cup tournament and progressed all the way to the final. That team is the Netherlands - they did it in 1978 and they've done it again this year. Can they become the first team to finish the tournament undefeated? In addition to the occasions mentioned above, the undisputed title has also been won outside of the World Cup tournament. Italy were the first side to achieve the feat, in 1939, and also the last, in 2007. The full list of undisputed UFWC and WC champions is: Italy 1939 Uruguay 1954 West Germany 1958 Brazil 1958 England 1966 West Germany 1974 Argentina 1978 Italy 1982 Argentina 1986 Brazil 1998 Brazil 1998 (lost and regained the undisputed title in same year) France 1998 France 2000 Italy 2007 The name of either the Netherlands or Spain will be added to that list on Sunday evening. To throw another factor into play, Spain are also the current European Champions, so if they win they will be combined UFWC / WC / EC champions and unify all three titles. The only side to achieve that feat previously was France in 2000. [Correction: West Germany also achieved this in 1974.] But let's put the statistics aside for a moment and reflect on the match itself. This is a game between two teams that play football they way it is meant to be played - pass and move. Or at least they have tried to play this way. They've certainly been the two most attractive sides to watch over the course of the World Cup competition. Underdogs the Netherlands, overlooked by many who had not been following their UFWC form, have won every match at the tournament, including beating many pundits' favourites Brazil in the quarter finals. Spain lost their first match to Switzerland, but have subsequently won every game, including disposing of Portugal and Germany in the knockout stages. The two top scorers in the competition will be on the pitch on Sunday - Wesley Sneijder and David Villa have both scored five goals so far. They have been among the best players at the tournament, along with the likes of Xavi, Arjen Robben and Carlos Puyol. Oddly, the Netherlands and Spain have never met at a major tournament before. What a way to start, with a UFWC / WC unification clash. It's undoubtedly a difficult result to call (unless you're Paul the psychic octopus, who has plumped for Spain in the final after a 100% correct prediction record so far this World Cup). Spain will go into the game as slight favourites with the bookies, but this one really could go either way. This really is going to be fascinating, so book a place on the sofa, prepare the beer and snacks, take the phone off the hook, and enjoy. Who will walk away with both the CW Alcock Cup and the World Cup? Who will become undisputed unofficial and official football world champions? Netherlands versus Spain: not to overstate things again, but this just might be the biggest and best international football match of all time...
