A crazy transfer market has got even crazier, as Barcelona confirm they will sign Paulinho for €40m this summer from Guangzhou Evergrande. Barcelona's transfer policy has been questionable over recent years, though in general they haven't joined in and gone to the extreme levels like other clubs spending huge amounts on a single player. With Paulinho's transfer immediately placing him as one of Barcelona's most expensive transfers, here is the full list of the top ten highest fees they have...
Barcelona's €34m move for Arda Turan in 2015, scrapes him onto this prestigious list, though his form for the club ever since suggests Atletico Madrid may have had the last laugh.
Playing football part-time in between being permanently linked with Arsenal, Turan has made only eighteen La Liga appearances in each of his two seasons at Barcelona.
If Turan is to leave this summer, it surely wouldn't be for the €34m Barcelona shelled out for him two years ago.
Andre Gomes joined Barcelona for €35m from Valencia last summer, after heavily impressing in his two seasons at the club as he defied the hapless Gary Neville.
Despite being voted the worst signing of the season by Marca, Gomes featured regularly for Barcelona last season though often as a utility player in a wide range of positions.
He doesn't appear to be essential to Barcelona's plans, and his future at the club may well depend on the signing of Philippe Coutinho.
Looking back on Dani Alves' transfer to Barcelona from Sevilla in 2008, the €35.5m seems like a brilliant deal as he went on to win everything at club level and become arguably the best right-back in the world.
Having very little interest in any form of defending, Alves spent eight years marauding down the right wing at Barcelona before leaving for Juventus last season.
His transfer to PSG ahead of this season proves the 34-year-old is still one of the very best in the world.
Barcelona naturally couldn't resist signing a player dubbed as the 'New Maradona' and signed 19-year-old Javier Saviola from River Plate in 2001 for €35.9m.
After a good first couple of seasons at Barcelona, Saviola increasingly found himself out of favour and was sent out on loan to Monaco and Sevilla.
At the end of his contract with Barcelona in 2007, Saviola made the bold decision to sign for Real Madrid, where he failed to make an impact.
Marc Overmars moved to Barcelona in a combined fee with Arsenal team-mate Emmanuel Petit in the summer of 2000, with Overmars believed to have cost €40m.
He made his debut for Barcelona against Arsenal in a friendly, but was substituted early on due to injury.
This was a sign of things to come, and after four years in which he didn't win a trophy at Barcelona, he was forced to retire in July 2004 due to a persistent knee injury.
David Villa's move to Barcelona in 2010 from Valencia for €40m was a transfer that made sense, with Villa having proven himself to be a proven scorer in La Liga over the previous decade.
The Spaniard struggled with injury, missing most of the 2011/12 season after breaking his tibia, but still managed two La Liga titles and a Champions League in his three years at the club.
After spending a season at Atletico Madrid, David Villa has spent the last three seasons proving he is still too good for the MLS.
Don't adjust your screen, you're reading this correctly.
Paulinho will be Barcelona's fourth most expensive signing in their history. The €40m move from Guangzhou Evergrande is a huge surprise, after a tough spell at Tottenham and then three years in the Chinese Super League.
It appears unlikely that PSG will move in to meet the €120m release clause of this particular Brazilian at Barcelona.
Zlatan Ibrahimovic signed for Barcelona in 2009 from Inter, in a €69m deal that saw Samuel Eto'o go the other way.
Ibrahimovic would stay in Spain for just one year, scoring sixteen La Liga goals as Barcelona edged out Real Madrid for the title.
Having played for Juventus and Inter earlier in his career, the Swede was obviously keen to tick off AC Milan too and joined them ahead of the 2010/11 season.
Luis Suarez's €82.3m move to Barcelona from Liverpool in July 2014 made him their second most expensive signing in history.
He's proved to be worth every penny with 121 goals in 148 games for Barcelona. In the 2015/16 season, Suarez won the European Golden Shoe as well as leading La Liga for both goals and assists across the campaign.
Neymar is Barcelona's most expensive in their history, believed to have cost €86.2m from Santos when he signed in 2013.
Forming an incredible partnership with Luis Suarez and Lionel Messi, Neymar appeared destined to become Barcelona's main man within the next few seasons.
However, a shock transfer to PSG this summer, for a €222m that made Barcelona's initial fee seem measly, means that the Brazilian will spend the peak years of his career away from the Spanish club.
