Zebina is an inconsistent player who usually prefers to use his muscles then his brain. I was completely with selling him before the start of the current campaign, and my theory was proved to be true at the beginning of the season. But he started to improve at a regular basis and he became our regular right back. I see that Ranieri preferred Zebina over Grygera in many matches this season, not because the former was simply better but because the latter was placed mainly at the centre defence (out of his position), thus he didn't perform well. A thing which made Ranieri loss confidence in him. Do you remember our match against Fiorentina?
When Grygera was placed as a full back (left this time) against Genoa, he started to gain Ranieri's confidence again.
