Fabregas and Lampard. Both played for rival clubs at some point to improve their chances at winning silverware, and both played at Chelsea at some point. The latter with an even bigger contribution and playing time, and he left when he was well past his peak. Yet, because Cesc is here right now and Frank isn't, Cesc is all the rage and Frank should just cut all ties with the club? Doesn't seem fair, IMO.
