Juan Mata deal
The recent January transfer window did not prove to be as lively or as entertaining as some had initially predicted. However, Mata's move from Chelsea to Manchester United certainly raised a few eyebrows - particularly here at GMS Towers.
We just cannot quite get our heads around quite how quickly the affable Spaniard went from being undoubtedly Chelsea's top performer to being surplus to requirements at Stamford Bridge.
And there is also no greater sign of Manchester United's rapid fall of grace that Chelsea and Jose Mourinho appeared more than happy to let them have him.
Will they eventually live to regret it?
