On the question of defensive cohesion, I would like to raise a few salient points.
1. If you play Richards as a central defender, you can forget about defensive cohesion.
2. If you want to play a high defensive line and you play Lescott as a central defender, you can forget about defensive cohesion.
3. If you play Hutton at full back and instruct him to bomb forward, you can forget about defensive cohesion.
4. If you play Cissokho at full back and instruct him to bomb forward, you can forget about defensive cohesion.
5. What is the point of Westwood as a defensive midfielder?
