#5 The Absolute Steal
Samuel Umtiti: €60m
Yes, you read that right. Barcelona's first-choice centre-back can be bought for as "little" as €60m! In today's market, that is an absolute steal considering how good Umtiti has been for the Catalan club this season.
What's not to like? Passing? Terrific! Tackles? Well-timed. Interceptions? His positioning belies his age and experience at the top level.
Barcelona have been trying to extend his contract for a while now considering the number of clubs waiting to pounce on him. Judging by his performances, they better do it soon!
#6 The Lottery
Yerry Mina: €100m
Nobody knows how good Colombian defender Yerry Mina can be at Barcelona yet, considering this is the first time he has come to Europe. Having established himself in Brazil, the €11.8m signing has James Rodriguez's vote of confidence, though.
Mina is 23 and has a long career ahead of him. But it is too soon to judge him and come to terms with his release clause.
