Liverpool's transfer window by the numbers: goals, minutes, metrics

The 2025 summer window is closed, and the squad is locked in until January. From my perspective, it’s been a brilliant window, one of the best we’ve had in recent years. Not just because of the names we brought in, but because of the intelligent, data-backed strategy behind it. Across defence, midfield and attack, we didn’t just buy names, we bought profiles that fit Arne Slot’s system. Let’s break it down with the numbers.

Recruitment Hits Across the Pitch

At the start of the summer, I said I’d be happy with four or five new additions. We ended up with more than that, covering almost every part of the pitch except one. Slot had a hand in picking the players, and that trust in the data team with the coach’s endorsement is a huge part of why I’m so pleased. We may have missed out on Marc Guéhi, but that doesn’t drop this below a 9.5 out of 10 window for me.

Take Giovanni Leoni. He’s 18 now, but played 1,200 minutes in Serie A last season at just 17. A 63% aerial duel win rate, better than Guéhi, Gomez or Quansah. That’s significant. Availability? Tick. Durability? Tick. Passing intent? Tick. He was attempting vertical line-breaking passes from a struggling Parma side. His profile says development project, but his metrics are already more robust than Quansah’s. I expect Slot to gradually increase his minutes to around 1,500 this season.

Kerkez, who cost £40 million, was signed to do what he did so well at Bournemouth: fly forward and whip balls into the box, however he’s been asked to simplify things and focus on defensive solidity. It’s working. In back-to-back games, he’s stopped 100% of the threat coming down his side, handled the league’s fastest wingers without a fuss, and posted 80% duel success against Arsenal. His passing and third-man runs are improving game by game. The evidence is there in the below plot against arsenal is duel wins show he is stopping the majority of dribbles he faces.
