Ashley Cole has been at the centre of controversy for various reasons in his spell in the Premier League. He earned the title of - 'Cashley' from the Arsenal fans, thanks to his money-minded move to Chelsea.
A product of the Arsenal academy, Cole was a thorough Arsenal man who spent six seasons at his boyhood club. A season before he made a move to the other part of London, Cole had a secret meeting with Chelsea officials for which he was fined £100,000 by the FA.
Later, the Englishman signed a one-year extension with the Gunners but his wage demands forced Arsenal to sell him on a deadline day deal to Chelsea in 2006. Cole wanted £60,000 per week but Arsenal were ready to pay only £55,000. Chelsea swooped in with a £90,000 per week offer and lured the full-back to Stamford Bridge.
Cole later revealed that he felt like Arsenal were "feeding him to the sharks" as he was frustrated with the Gunners' resistance in offering him an improved deal. Till date, Arsenal fans hold a grudge against a player who once was one of their own.

The player claimed that he was compelled to accept the offer which further infuriated the fans to a great length. His transfer's impact was such that riots were held on the streets of Florence which left many injured.
When Juventus met Fiorentina the following season, Baggio refused to take a spot kick and was straight away substituted. As he was going out, he kissed a Fiorentina scarf to declare his love for his former club. He said at that time, "Deep in my heart, I am always purple." This was one of the most talked about transfer incident in the history of Italian football.
