These 5 players, all transferred in 2017, have given their clubs plenty of reason to be happy in that sense, seeing their market values increase the most.
5. Paulinho – £27m Increase
Market Value up 300% to £36m
Eyebrows were raised when Barcelona paid €40m to bring Brazilian midfielder Paulinho back to Europe after a spell in China with Guangzhou Evergrande.
But the Catalans are the ones now laughing. Although not a typical Barcelona player, Paulinho has been a revelation and has seen his market value, just £9m last January, absolutely rocket.
4. Goncalo Guedes – £27.9m Increase
Market Value up 344.4% to £36m
Portuguese winger Goncalo Guedes moved twice in 2017; firstly joining Paris Saint-Germain from Benfica in a big money January deal, and then securing a loan to Valencia in summer. Both moves have served to send his market value soaring.
Only recently 21 years of age, the youngster has impressed in Spain this season with eight combined goals and assists in La Liga. His future is very bright indeed.
3. Neymar – £45m Increase
Market Value up 50% to £135m
Although still way short of the £200m that Paris Saint-Germain actually paid for hi; Neymar’s market value is climbing rapidly and will no doubt soon eclipse that world record figure.
The Brazilian superstar has been a marketing dream for the six-time French champions; while on the pitch he has scored 11 times in 14 Ligue 1 games to help PSG run away from the rest.
