Liverpool's Summer Transfer Dilemma: Kaishu Sano's Potential Move

Liverpool’s quiet summer is starting to sound loud.

With just over a month left of the window, Victor Muñoz remains Liverpool’s only senior signing. For a club that briefed of a sweeping rebuild and “five or six” new faces, the reality is jarring. Arne Slot has gone, Andoni Iraola is in, yet the squad beneath him looks suspiciously familiar – and, if anything, a touch thinner than the one that finished the 2025-26 campaign.

Supporters have grown used to a daily swirl of names around Anfield. Most disappear as quickly as they arrive. A few, though, keep circling, fed by regular updates and the sense that Liverpool are simply biding their time before a late flurry.

One of those names is Kaishu Sano.

Midfield in flux, money on the table

Midfield was supposed to be Liverpool’s safety net. It is, on paper, their deepest department, yet it now feels like the most precarious.

Curtis Jones, Harvey Elliott and Trey Nyoni have all been linked with moves away. Lose even one of them and the balance shifts; lose more and the club are suddenly scrambling. The message from inside Anfield has been clear enough: departures will need replacing, and not with stop-gaps.

That helps explain the volume of links. Liverpool are casting the net wide and, crucially, they look ready to spend. Talks have reportedly opened with Paris Saint-Germain over Bradley Barcola, a move that would not come cheap and underlines that the budget is there if the right player appears.

Sano, though, will not be a bargain either.

Mainz lay down their terms

Mainz sporting director Christian Heidel has made sure of that. Asked about interest in Sano, he chose his words carefully but his stance was unmistakable.

“I won't comment on any rumours or any of the clubs mentioned. We don't have to sell Kaishū; we can afford to keep him,” he told Bild. “If he stays, there will be many happy people in the team, the club, and everywhere around it. But it's like always at Mainz 05. Should an offer come in that takes our breath away, we'll have to consider it!”

That last line is the key. Mainz are not desperate. They are inviting a statement bid.

The expectation in Germany is that any club wanting Sano this summer will need to put around £50 million on the table. In an overheated market, that figure no longer shocks. For a 25-year-old defensive midfielder established in the Bundesliga, it sits in the “painful but plausible” category.

For Liverpool, it would be a declaration that this quiet window is about to change gear.

The World Cup springboard and a Gravenberch challenge

Outside Japan and the Bundesliga, Sano’s rise has gone largely under the radar. The 2026 World Cup offered a glimpse. Since arriving in Germany for the 2024-25 season, he has quietly become one of Mainz’s pillars.

Eighty-four appearances in all competitions. Eighty of them as a defensive midfielder. Seven goal contributions in the 2025-26 campaign alone. The numbers don’t scream superstar, but they do shout reliability, availability and a player growing into his prime.

Drop that profile into Liverpool’s midfield and the picture sharpens. Sano would not arrive to make up the numbers. He would walk straight into a duel with Ryan Gravenberch for minutes at the base and in the engine room, pushing standards and forcing Iraola into real selection calls rather than default choices.

He brings bite, structure and a platform. Exactly the sort of presence that allows Liverpool’s more expressive players to roam.

There is a catch.

The homegrown headache

Sano solves one problem and sharpens another. He would strengthen the midfield pool, but he does nothing for Liverpool’s homegrown quota.

If Curtis Jones were to leave and Sano arrive, the club would still need another midfielder – this time one trained in England – to keep the squad compliant and competitive. That is the tightrope Liverpool are walking: every non-homegrown signing has to be weighed against the spaces available.

So the question for Liverpool is not just whether Sano is worth £50 million. It is whether they can afford that fee, another midfielder, and still address needs elsewhere in the squad in a single window that has barely started to move.

The clock is ticking. The squad looks lighter. And if Liverpool truly believe Kaishu Sano is the anchor for Iraola’s new era, they may soon have to decide whether this is the moment to finally break their silence.
