Keane was the type of player that you didn't notice on the pitch while playing, but when he was gone, it was definitely noticeable. Comparing Keane to Zidane is like comparing Claudio Taffarel to Pele. Zizou was an attacking midfielder, and Keane was a holding, defensive anchor. When Keane left United, he left a void that has yet to be filled, with players like Owen Hargreaves tasked to fill it. Darren Fletcher has progressed in recent seasons, but with his viral problems it has been a setback. Gerrard never won a premier league title, and Keane has more that a couple.
