Well that Skrtel equaliser was a byproduct of our zonal marking on set pieces. Sometimes it works, but when it doesn't it makes our defence look bloody stupid, doesn't it.
They basically allow the opponent's most dangerous players to have a free run inside our box. This was always going to happen, even if Liverpool were 3 men down.
We should have some sort of hybrid kind of marking on set pieces. Leave some players covering dangerous zones such as the 9 yeard box edges, but always mark their best headers closely, please. Otherwise it looks just amateurish. That's how it looks, really.
If Allen or Coutinho scored with a header there, you could at least understand why they weren't marked. But a free run and free header for their centre halves? Really?
Anyway, this is the kind of thing we have to live with as long as Wenger is with us. I don't see him changing it now, especially mid-season.
I was watching bits of Stoke vs Chelsea yesterday, and we just have to admit that Mourinho knows how to adjust his team for each different scenario. A cold Monday night at Stoke, as they say, is not a problem to him. Mourinho knows how to fight fire with fire and when you show Stoke that two can play at that game, you will eventually edge them due to superior technical quality.
This is one of the things we should be learning from them.
