Most of the times it did in my opinion. Harry knew/ knows that for some reason, we can't defend as a unit like Chelsea/ Stoke etc so our best form of defence is trying to attack and keep the opposition pinned back.
I'd love to win things too and I hope AVB is the man to do it but the decisions he's made against Norwich and Southampton (can probably name others but can't be ars*d) have been poor. At Southampton he tried shutting up shop at 60 mins by bringing Jake on, leaving Southampton to attack for a good 25/ 30 mins and we were lucky in the end to leave with 3 points. Then against Norwich he made a stupid sub by bringing on Jan into CM which allowed them to come forward more as Carroll was having a tidy game making forward passes and contributing to attacks, Jan was arguably at fault for both goals too and we ended up losing a game that we controlled with ease. With all due respect, both these teams are the type we should be beating comfortably without the need to sit back and grind out a win.
What's the point in having a plan B if it's not effective?
I am mostly in agreement with this, SoS, but a proper manager (which I hope AVB is) would sort out our weaknesses so that we didn't just have one plan. When you introduce a new way of playing it is not likely to work briliantly on Day 1, especially when you don't have your best players available but if you alter it too much to suit circumstances it won't work so well in the long run. Personally I think starting with Sandro and Dembele with Parker in the wings when we want to go more defensive would work fine. Whereas Sandro and Thudd with Livermore in the wings is a lot weaker. But I still think it is right to play the same system whatever the personnel so that the players can get used to it. We need to use the next transfer window to make the squad more suitable as well. But with Kaboul, BAE, Parker, Dembele and Ade back and Walker, Sig and Dempsey performing more like they did last season we have a very good chance of hanging on to fourth or better and nicking one of the cups.
