You don't get many signings like Cesc Fabregas. A creative mastermind who had sworn allegiance to a direct rival club. To be honest with you, when the rumours circulated in 2014 that he would be joining Chelsea, I refused to believe it might happen.
His arrival shocked several Arsenal fans. Their feeling of betrayal warmed the hearts of Blues supporters as it would any rival fan. And given the deal cost a bargain £29.7m, it rubbed salt in Gunners' wounds.
He was not the first player to have the 'judas' label attached to him by Arsenal fans, with Samir Nasri's move to a new-money Manchester City team causing uproar. And of course there was Robin van Persie, Manchester United's greatest steal. Thierry Henry will always be considered an Arsenal legend and yet even he prompted a feeling of betrayal when he left to join Barcelona.
