On the top there, we have Gravenberch. On the bottom, Wirtz. Both had the majority of their possession on the brink of the attacking third - i.e. the attacking midfielder space. And that's a problem, given only one of those players is supposed to be an attacking midfielder. The even bigger problem is that the player with the deepest and most central 'red zone' is Wirtz - the absolute opposite of how things are supposed to be. That even translated to defence! Both Newcastle goals came from Gravenberch pushing into the attack, losing the ball, and Liverpool being ill-equipped to stop a counter-attack. What was the plan there? For Wirtz to offer defensive cover? Because there are about 50 reasons why that's a tactically awful idea. Now, to Iraola's credit, he plainly didn't like it either. The pair have not started a game together since, or at least hadn't until the Fulham clash on Saturday. So let's have a look at their heatmaps from that one:

Once again, Gravenberch top, Wirtz bottom. The change here is stark, with Wirtz much further forward on average than his teammate and dominating at least one area of the pitch. Virtually all of his possession came in that 'no.10 space', too. But here's the catch. Forcing Gravenberch to sit deeper completely neutered him and he offered essentially nothing across his time on the pitch. Liverpool's sitting midfielder - someone looking to control the game in possession - cannot be attempting 30 passes in 67 minutes. Kostas Tsimikas, for comparison, attempted 31 in his 45 minutes at left-back. We're not sure the pair of them can play together. Wirtz's game is one that strips Gravenberch of his natural qualities, while the German is also not the right player to adapt to Gravenberch. Dominik Szoboszlai, when he was playing as the no.10, can do it better. He naturally drops deeper to get his foot on the ball, so covering Gravenberch's runs forward is comfortable - or at least more comfortable. But Wirtz? He just doesn't mesh with Gravenberch at all. And that's an enormous problem for both when they've eached signed deals for enormous money within the last 18 months.
