Right, but the CB's are Evans, Smalling and Jones, which is one good but not expansive passer in Evans, one probably below-average one in Smalling and an average one who can carry the ball forward into spaces better than most in Jones. You've still got 3 players who can basically be allowed the ball without hurting us. There's a reason most teams playing 3 at the back successfully have had a top passer of the ball who can't be ignored or he'll hit someone with a long pass over the top or generally distribute well enough to improve the attack, like De Boer, Koeman, Rafa Marquez or a type like that.
We will play teams this year who sit 10 men behind the ball and give our center backs time on the ball, and they'll have one less option than normal going forward, since there will be another one of them along side. That can be alleviated a bit by having the 2 wider ones spread very wide in possession into almost traditional fullback areas, which is partly why LVG is presumably looking for a left-footer.
It just worries me that the top teams like Bayern, Madrid and Barca all will be fielding 9-10 outfield players who are great on the ball and we'll be closer to 7 or 8.
