#2 Yerry Mina
Yerry Mina was signed by Barcelona from Palmeiras for £10.6m in January but has only made a total of six first-team appearances since then. He failed to settle in Spain and has now found himself in the reserves.
His career has been revived somewhat by his stunning performances for Colombia in the World Cup, where he scored three goals in three games - no mean feat for a central defender. In the tournament, Mina played alongside Tottenham's Davison Sanchez, and the pair were a force to be reckoned with.
According to Transfermarkt, Yerry Mina's value increased by £10m thanks to these performances, meaning he's now worth a minimum of £18m.
Where might Yerry Mina go?
Mina has been linked with Wolves, Everton, Lyon, Boca Juniors, and most recently, Manchester United. Out of the bunch, it's quite easy to predict which club he'd favour if given the choice.
The Guardian have stated that Yerry Mina is set to "become the latest member of Jose's happy family".
