Paul Pogba's world-record £89million move from Juventus to Manchester United has further highlighted football's riches, with transfer fees likely to balloon in price even more in the near future.
Here Press Association Sport looks at the most expensive signings so far in the history of the game, in each position.
GOALKEEPER
GIANLUIGI BUFFON (£32.6million)
Juventus paid a world-record fee for a goalkeeper to lure Buffon from Parma in 2001, with the Italian still number one with the Turin side and with Italy 15 years later.
DEFENDERS
Right-back: DANI ALVES (£27.5million)
The flying Brazilian right-back was the target of a stealthy swoop by Barcelona on Sevilla in 2008, and spent eight fruitful years at the Nou Camp before moving on to Juventus this summer.
Centre-back: DAVID LUIZ (£50million)
The Brazilian is the most expensive defender on the list after his move from Chelsea to Paris St Germain was announced in June 2014.
Centre-back: THIAGO SILVA (£33million)
As with most deals, the fee was officially undisclosed with Silva joined PSG from AC Milan in 2012, but it was widely reported to be a deal worth 42 million euros, which at the time worked out at £33million.
Left-back: LUKE SHAW (£27million)
Shaw played for England at the 2014 World Cup aged just 18 before joining Manchester United.
MIDFIELDERS
Right midfield: ANGEL DI MARIA (£59.7million)
A statement signing in its day, Louis van Gaal felt he had acquired the playmaker Manchester United needed in 2014 after making a huge investment in the Real Madrid player. It proved far from successful though, as Di Maria was shuffled off to PSG a year later.
Centre midfield: PAUL POGBA (£89million)
Not a match-winner in the typical sense, but Manchester United believe Pogba will add the midfield quality they have lacked in recent seasons and turn the team into champions again, four years after he left for a tiny fee to join Juventus.
Left midfield: JAMES RODRIGUEZ (£63million)
Real Madrid threw Monaco an estimated 80 million euros (worth £63million at the time) for the Colombian after he dazzled at the 2014 World Cup.
FORWARDS
Right forward: CRISTIANO RONALDO (£80million)
Ronaldo developed from a tricky winger into a goal machine while at Manchester United, and Real Madrid shattered the transfer world record in 2009 to land the Portugal star after a long pursuit. He has since become Madrid's all-time leading goalscorer.
Centre forward: GONZALO HIGUAIN (£76.5million)
Juventus paid the release clause in Higuain's Napoli contract this summer to land the Argentinian who last season scored an all-time record 36 goals in a Serie A season.
Left forward: GARETH BALE (£85.3million)
The Welshman shone in the Premier League and Europe for Tottenham, and Real Madrid had to break the world transfer record to take him to the Bernabeu in 2013. Madrid have secured two Champions League trophies during his three seasons at the club.
TOTAL COST: £623.6million
