That's it, we've struggled defending in our box with three centre halves, how would two do?
Whilst I respect and agree with many of your observations , I believe it’s that kind of thinking that has got us into the situation we are in .
The reality is that a solid back four supported by a competent holding midfielder can be a more effective defensive unit than the system we use . In our system, once we get the ball over the half way line ( not very often these days ) , the two wing backs are expected to abandon their defensive duties and supplement the attack since it is short on numbers .
When this happens , two of the centre backs move wide into the full back position leaving the lone centre back ( Egan ) badly exposed and susceptible to the quick counter attack ( see Villa , Leicester et al )
On the other hand , if the opposition play it wide , our wide central defenders are often exposed two against one trying to keep things under control until the wing backs charge 70 yards back down the pitch to try to support them .
With a successfully operated back four and holding midfielder both these scenarios are nullified but , even more importantly , it provides the opportunity to include more possession based and attack minded players further up the pitch who ( whisper it quietly ) , might even lead to us scoring a few goals .
Finally , I don’t subscribe for one moment to the ridiculous idea that we only have players who can operate in a 3-5-2 formation , nor do I believe that all the other clubs in the PL have a group of defenders who are far superior to ours .
I could name at least 10 clubs who turn out defenders week after week who are nowhere near as good as some that we have . The difference is that they don’t have to spend 80 out of the 90 minutes defending and play for clubs that have not forgotten that scoring goals is the best way to win football matches .
