We're lucky Mata's liableness didn't cost us the Champions League and FA Cup in 2012 or Europa League last season. The only reason we fell apart last season was because of a combination of poor squad depth and the shortsighted sacking of Di Matteo which in effect caused a toxic atmosphere. Mourinho is just a proud man and won't admit to his mistake. Shame he's doing this to the classiest player this organization has seen since Zola. Mata is the sort of player you build your system around to conceal his flaws.
