The point made was a fair one, we aren't going to dominate possession v Arsenal anytime soon. We need to find a way to get the result and it's true that they do struggle against a packed defence. Think it's pretty likely we will be pushed deep for long spells and then look to counter when the play breaks up. I don't think being at home has much bearing on it, neither does them losing 2-0 against West Ham.
Of course being at home should have a bearing on it, as should the fact West ham beat them 2-0, and Liverpool made their defence look a joke in the first half when they tested it and Callum Chambers will be playing centre half again today.
