Here, Press Association Sport looks at five other players who cost a lot more the second time around
NEMANJA MATIC
Initially cost Chelsea £1.5million from MFK Kosice, and was then swapped for mop-topped maverick Benfica defender David Luiz two years later
The Blues saw the error of their ways in 2014 when they shelled out £21m to bring the Serbian midfielder back to Stamford Bridge.
GRAEME LE SAUX
Sold by Chelsea to Blackburn for just £700,000 after throwing his shirt at manager Ian Porterfield in protest at being substituted, Le Saux became the most expensive defender in England when the Blues forked out £5m to bring him back.
DANI CARVAJAL
The right-back had not made a single first-team appearance for Real Madrid when they sold him to Bayer Leverkusen for 5m euros
However, the canny Spaniards inserted a buy-back clause just in case he turned out to be any good
Which he did
Carvajal returned a season later for 6.5m euros and is now a regular among the Galacticos.
BOBBY ZAMORA
Joined West Ham as an apprentice but was released as a 17-year-old along with a group of players including Paul Konchesky
Five years later the relegated Hammers brought Zamora back as part of a big-money deal which saw Jermain Defoe sold to Tottenham
Played in the 2006 FA Cup final - alongside Konchesky, who cost £1.5m from Charlton.
ALAN SHEARER
Newcastle had a young Shearer growing up on their doorstep and offered him a trial
However, the story goes that they put him in goal
Southampton had the foresight to play Shearer up front and promptly signed the future England captain
When Newcastle finally got their man it cost them a then world-record £15m.
