If someone had said on December 31st that we'd only buy a single player in January, and it would be an attacking midfielder, I'm not sure anyone would have been happy.
Mata is a wondeful addition to the squad, but for me he's hasn't filled in the gaping holes we have preventing us from putting a real run together. I'm not sure if we'll manage anything else this window, but despite all the fun of Mata in a helicopter, I'm not convinced it will have been a 'good' window for us.
LB and CM remain such huge problems...
