He absolutely was outstanding in that season. As were Leicester players last season, i'm not sure how that validates your point in any way. Edit: Stats, match reports, even our results speak for themselves. He played to his strengths and those strengths provided an element of balance and security to our team that we hadn't seen since Gilberto Silva.
It's fine not to like him, but to disregard what he brought to the team in that season is just lazy and ignorant.
@Castiel what? English please.
