Several have 'got away' from us since the takeover starting with Berbatov, Terry, Kaka (3 dodged bullets IMO), Villa and Eto'o. Followed by De Rossi, Sanchez, Krasic, Lavezzi, Hazard, De Rossi again, Martinez, Van Persie, Isco, Cavani, Pepe and most recently, Fernando.
The bottom line is, you miss out on players. With Hazard, we didn't want to be held to ransom with ridiculous, extortionate agents fees and bonuses. He may well turn out to be worth it, and probably is right now, but we didn't sign him and we have other players. We have Nasri, Silva, Navas and Milner. We have Aguero, Negredo, Jovetic and Yaya Toure. We have Zabaleta, Fernandinho, Kompany and Hart. Are these the players that got away from Chelsea? or United? or Arsenal? No. They are just our players, and Hazard is Chelsea's player. And until he runs down his contract or becomes available for transfer it will remain that way.
