Exactly. Ivanovic is still 26 and Alex is 28. Terry looks like he can go strong for 2 more seasons at least. It's simply too premature to think about a new centre back when we've got problems in midfield and attack! Before November we'd conceded the least amount of goals. Terry, Ivanovic & Alex are more than capable of handling their duties in the back, there's simply no need for change that. That £20million could be saved, and perhaps saved for the signings of Lukaku & Sanchez in the summer (if the reports are true). The only centre back we could even consider is someone like Samba who's cheap and reliable (in case we do get an injury crisis back there.)
