TheMaraudingDog I still think Terry needs to be in the squad.
Rio is always injured
Jones prone to mistakes and has played his best games by far in centre mid
Cahil has been really poor the last 6 months. Needs to prove himself one at Chelsea but not been played.
IMO the best two for consistency this season have been Smalling and Lescot.
I agree on a footballing front that I'd have Terry in the side for the Euro's (all things remaining as they are - was going to dig up the old squad discussion the other day to see how things may have changed). You need a steady and experienced influence in a back four and he's actually recovered some form this season.
If Fergie actually played Jones at centre back for a few months he might well be the answer but, as you say, he's not looked totally convincing there (Fergie's fault if you ask me).
We have some decent options back there but ultimately I do think it's about who can play with Terry.
Having said that, now he's been stripped of the captaincy I'd be tempted not to take him at all. That might not be the best for our success this tournament but if we can get Cahill and Lescott (for example) to gell over the next few months it might be the best thing alround.
