10. Jeremy Mathieu
Barcelona’s trophyless 2013-14 season can be adduced to some slack defending at the back that were greatly exploited by rival teams. So in a quest to shore up the porous rearguard coupled with a replacement for the outgoing Carles Puyol, te recently sacked Sporting Director Andoni Zubizaretta shelled out £20 million on Jeremy Mathieu and it proved to a coup.
The Frenchman has spent last 6 years of his career at Spain and plausibly so, attuned to life at the Catalan capital without any glitches. The 30-year old has greatly cemented the void left by Puyol and has been impressive thus far.
