Selling a defensive midfielder for £30m is good business as we should be able to pick up an adequate one for £15m or less, but it would be suicidal to do it in January as we would need to bring a replacement in quick and get them bedded in very quick, otherwise do you really think Aquilani will come good playing alongside someone as mediocre as Lucas?.
It's all very well looking for these magical players that can unlock defences, but it is our defense that is letting us down and without Masch god knows how many more times our back four would have been torn apart.
