There's no denying that our defence has been horrendous this season. For me, it's not to do with the midfield. I think Bentaleb, Mason, Stambouli and Dembele, even Lamela and Eriksen have worked hard in midfield to win-back possession. The amount of goals that can be attributed to individual mistakes by our defenders is, however, alarming. I think we have too many players in our back-line that switch off. Walker has done this all through his career and has never cut the brain-farts out of his game. Vertonghen is the same. In the last two seasons, he's always liable for a major error that leads to a goal-scoring chance. Whether that is a missed header, a stupid lunging tackle or just getting caught in possession on the edge of our box. Dier is a kid and there's hope for him. I see a lot of potential there, but he needs leaders around him. Rose has also improved. He's seeing the gradual improvements to his game season-on-season that Walker just isn't getting. Walker is the same player he was when we first bought him. He's stagnated.
For me, if we had one real organiser at the back, a real leader, we'd do better. I think as much as he's not the best player in the world and has made a few howlers, I can see why Fazio was brought in. One, he's a beast in the air and clears everything. This is so important for relieving pressure, particularly that kind of late bombardment when you're defending a narrow lead and the other team gets desperate. One reason why other teams seem so much more comfortable in this situation, is almost all the Premiership teams have at least one defender, who is dominant in the air and heads stuff away from the box. Our only such player is Fazio and he isn't in the team right now. Secondly he's an organiser. Less of the stupid stuff like everyone else but Walker stepping up to play off-side, or Dier and Verts going for the same ball happens when Fazio is in the team.
I think we need a calmer, more intelligent player at the back. So many times we have 2 to 3 defenders go ball-chasing and leaving someone free. It takes someone to step back and see the bigger picture, the bigger threats.
I don't rate Vertonghen at all. I think he's possibly the most overrated player in the squad. He cannot defend. He's a good footballer, but the amount of times he just gets sucked to the ball or is in no-mans land is frightening for someone talked about as being world-class at times.
