Luis Figo's arrival at Real Madrid 20 years ago is still the most contentious transfer EVER, beginning with a £1.4m promise on a piece of paper and ending with a pig's head thrown on the Nou Camp pitch... and it kick-started the entire Galactico era

It's hard to think of a transfer that compares with it. The Luis Figo switch from Barcelona to Real Madrid that took place 20 years ago this summer was the ultimate football betrayal.

So loaded with symbolism, vitriol and rancour, it makes Sol Campbell going from Tottenham to Arsenal look like Morecambe and Wise joining ITV from the BBC in the late 1970s.

The hurt on Barcelona's side has never really gone away. In the run up to the 2015 Champions League final between Barcelona and Juventus in Berlin, the club requested that Figo not represent them in a legends match.
