#8 Jeremy Mathieu – Barcelona – £7.65m decrease
Jeremy Mathieu’s presence in this list would not come as a surprise to Barcelona fans, with the Frenchman hardly a fan-favourite. It’s a steep decline in reputation for Mathieu after moving to Barcelona, but that is hardly surprising considering he is 33 years old.
When Unai Emery signed Mathieu for free in 2009, Valencia fans grew to love the centre-back quickly – with his all-action performances often a lone shining star in a declining Valencia side. That prompted Barcelona to part with €20 million for the Frenchman in 2014, and set a staggering €50 million as his buyout clause.
You’d be hard pressed to even find a Chinese Super League club willing to part with that amount for Mathieu now. The Frenchman has only managed 8 appearances for Barcelona this season, and coupled with him turning 33 last October, Mathieu experienced a 64.3% drop in transfer value.
Jan 2016 value: £11.9 million
