The Premier League may be the most in demand and richest in world football, but there's still an awful lot of money around Europe with other clubs. La Liga is perhaps the top flights biggest challenger with their top clubs throwing some serious funds about in the transfer market over the last few years. Real Madrid and Barcelona dominate the transfer records for the most money spent on players but the rise of Atletico Madrid under Diego Simeone over the last few years has seen their wealth and spending power increase - with them attracting some magnificent players.
Atletico Madrid's success saw them manage to overthrow the big two back in the 2013/14 season to win La Liga against all odds and they've since made the final of the Champions League Final, becoming a major player in Spain. Well this weekend they take on Barcelona at their new Wanda Metropolitano home and it looks like a mouthwatering match on paper, with just a point separating the two clubs at the top of the La Liga table - so we're all set for a classic. Lionel Messi is back fit and in training too for Barcelona so it should be some spectacle in the Spanish capital.
In the build up to the clash we've put together a quiz that'll really test your knowledge on these clubs. We want to see if you can name each of their record transfers, with their 15 most expensive acquisitions listed. The majority of these have come in their recent history so we're expecting some pretty big scores here - 25/30 would be a fantastic effort! Give it your best shot below and tweet your scores into us @FootyAccums to see how you compare with the rest of our followers - good luck!
