On Saturday evening in the Basque hills, Spanish giants Real Madrid will play in front of a capacity 6,000 crowd in a David against Goliath clash.

Their opponents, Eibar, are something of a miracle in footballing terms - they were promoted from the Spanish second division last season, despite having the smallest budget in the league.

The Basque town can boast just 27,000 inhabitant, making it the same size as Fleetwood - a sign of their surprising progress.

Real Madrid will bring their usual array of stars, including world record breaking signings Cristiano Ronaldo and Gareth Bale in their squad, whereas Eibar can boast 10,000 euros summer acquisition Javi Lara and a collection of free transfers, many of which have played for the minnows in regional leagues.

Eibar have an identical azulgrana colour scheme to Barcelona, but they are a world away from their more established counterparts, even having to come up with 2.1million euros in order to reach financial stipulations and take their place in the Spanish top-flight.

Real Madrid can fit 81,000 into their Santiago Bernabeu stadium, a mere 75,000 more than Eibar can get into their tiny Ipurua ground, which has recently added some temporary seating to boost capacity.

When Ronaldo was presented to the crowd in the Spanish capital in 2009 after signing for £80million from Manchester United, there were 80,000 fans inside the stadium, almost three times the population of Eibar.

The Portuguese forward takes home around £380,000 a week, close to £20million a year, whereas Eibar's entire budget is less than £15million. Real Madrid have set their spending at £43million for this current campaign.

No Eibar player will take home more than half-a-million euros this season, as their mainly Basque squad battle to stay in the league, but are surpassing expectations, currently sitting tenth.

Eibar striker Mikel Arruabarrena said of the occasion: "It's going to be a unique experience with the stadium full playing one of the best teams in the world."

Real Madrid are one of only three sides to have never been relegated from the Spanish top-flight, along with Barcelona and Athletic Bilbao, but this is Eibar first-ever campaign at this level.

The club from the capital have 10 European Cups to their name, as well as 32 La Liga triumphs in their history, whereas Eibar's trophy cabinet contains last year's second division title and nothing else.

Emirates pay 30million euros for the privilege of having their logo on the Real Madrid shirts. At Eibar, they are currently sponsored by a local ironworks for a fraction of that.

Whatever happens on Saturday, it will be an experience never forgotten by the players and crowd alike.
