That's exactly what it is, and quite honestly I don't see it changing significantly any time soon. In fact, I'm far from convinced it'll have changed significantly in 12 months time even after a major transfer window, because our style of play is too easy for teams in this particular league to overcome. If you're a shambles like West Ham or you want to come out and try and give us a game like Arsenal, then sure, like as not we'll tear you a new one, but if you want to sit deep, keep your discipline, and then counterattack with power and pace then you'll turn us over again and again.
Put simply you cannot defend in this wide open fashion in English football, no matter who your defenders are, because virtually every team has got a lummox to relieve the pressure (Lukaku, King, Wickham, Giroud, Vokes, Slimani, Costa, Kane, Rondon, Carroll, Llorente, the list goes on and on) and midfielders with the pace and determination to get downfield and take advantage. Chuck in a keeper, who looks genuinely incapable of saving anything, and you've got a recipe for fuck all. If Pep thinks we were unlucky in any way today he's living in a fantasy world. We got precisely what we deserved (not for the first time) for a fatally flawed game plan, and we were undone again by opposition who didn't even have to be good to beat us, just organised and committed.
