OK, let's talk about the game. Champions League games are always interesting because of the clash of styles and different football cultures and here Inter were able to pose certain problems for us that we don't usually encounter in the EPL. I rewatched the 2nd half just now because I missed some parts of the game live and on rewatch it was striking how Inter were able to bypass our midfield completely not by trying to hit long passes in behind our high line, as we usually see, but by building exclusively down the flanks. Here's a screenshot illustrating the point:
There is not a single Internazionale player in the middle of the pitch! Inzaghi made a tactical tweak at half-time with LCB Bastoni (#95 at the bottom of your screen) moving to the quasi wing-back role during the build-up, while Perisic joined the forward line, playing on Trent's shoulder (in this case Dzeko happens to be in that position while Perisic is in his own half as he just tracked Salah's run, but the point stands), while the rest of the midfielders (including nominal AM Calhanoglu) drop into a defensive "shield" that is meant to stifle our quick attackers (Ancelotti's Napoli used something similar against us a few years ago). This does not seem all that sophisticated – just keep 4-5 players back at all times, 3 up front and a couple of shuffling wingers to connect both groups, but as with Italian cookery, sometimes simplicity is best. Fabinho, Thiago and Elliott have nothing to do and no one to tackle (I think Elliott should be much closer to Bastoni in this position), the front 3 have no space in front of them if the ball is turned over and Trent is constantly overloaded. A less talented and somewhat pedestrian Inter team was able to cause us serious problems just by the virtue of their tactical plan as well as, it has to be said, impressive battling midfield performances by Vidal and Brozovic. What they lacked in their periods of dominance was decision-making in the final third; whether it was lack of confidence or belief, they literally passed on the chances to land a real blow.
Talking about lack of confidence, I think it's fair to say that despite having a fully fit squad, we don't have many players near their peak form right now. With the exception of the CBs, Alisson and Fabinho, the rest are either recovering from a grueling AFCON or gaining sharpness after an injury or still finding their feet in the new team like Diaz. I think the likes of Ox and Minamino are objectively in a better run of form than Salah and co. at the moment, but of course Klopp knows that he needs to play his stars into sharpness for the decisive battles ahead.
Maybe we should talk separately about Trent. I usually scoff at the English pundits excoriating the defensive side of his game, but on this occasion he has no defence from me. Every single time Perisic squared up to him 1 on 1 he was able to put in a cross or slide in teammate – this was like playing against a training cone. Even worse, the decision-making and positioning were all wrong too – Trent sometimes has these games where he seems to move around in a daze and this was definitely one of them. Like that moment when Van Dijk's clearance landed at his feet and he "crossed" the ball right back into the danger zone, which created a chance for Vidal and led to a sustained period of Inter pressure – what the hell was that about?
Despite all these problems, Trent's ability to spring attacks from deep was still important for us and this is where Klopp is different from other managers – his trust never wavered and instead of berating and taking off his poorly-performing right back, he correctly identified the reasons for his underperformance and created conditions for him to focus on the things he does well. On came Keita who covered the space Trent couldn't and finally was able to block a Perisic cross and Hendo who initiated quick passing combinations that pushed Inter back and allowed Trent to get forward and do what he does best – an assist from a corner (that he won) and a cross after a free-kick (that he also won) that led to Van Dijk's knock-down for the 2nd goal. We were lucky in some moments, like with the Firmino goal that came a few minutes after Dumfries missed a header from an almost identical short corner routine, but ultimately what won us the game was the excellence of the CB pair that allowed us to bend but not break when we were under the cosh, Klopp's calm thinking and the quality we were able to summon from the bench.
