Liverpool's Summer Transfer Dilemma: The Kaishu Sano Situation

Liverpool’s quiet summer suddenly has a very expensive focal point.

With Victor Munoz still the only signing of the window, a fanbase that had been primed for a sweeping rebuild is watching the days tick away and wondering where the revolution went. Arne Slot has gone, Andoni Iraola has arrived, and yet the squad that limped over the line at the end of 2025-26 looks, if anything, thinner.

Rumours swirl daily around Anfield. Names come and go. A few, though, refuse to leave the conversation. One of them is Kaishu Sano.

A rebuild that hasn’t started

Liverpool went into the summer expecting to reshape half a team. Five or six new faces were spoken about with the kind of certainty that usually only surrounds medicals and shirt numbers.

Instead, the departures column has dominated the discussion. Curtis Jones, Harvey Elliott and Trey Nyoni have all been linked with moves away, even as midfield remains the deepest area of the squad. Depth on paper, though, is not the same as balance on the pitch, and Iraola cannot afford to see bodies leave without proper replacements.

Behind the scenes, Liverpool have clearly not shut the wallet. Talks have reportedly opened with Paris Saint-Germain over Bradley Barcola, a deal that would not come cheap and underlines that the club are still prepared to operate at the top end of the market.

Sano, however, would test just how far they are willing to go.

Mainz lay down their marker

Mainz sporting director Christian Heidel has made it clear: anyone wanting Kaishu Sano will have to pay a premium.

“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,” Heidel told Bild, before delivering the line that will echo around recruitment meetings at Anfield.

“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!”

Translated into transfer-market reality, that breathless offer looks to be around £50 million. For a 25-year-old defensive midfielder with growing Bundesliga pedigree, that figure sits firmly in the “serious but not outrageous” bracket in today’s inflated market.

For Liverpool, though, it would still be a statement. A big fee, for a specialist profile, at a time when several other areas also need attention.

The World Cup breakout who doesn’t solve everything

Outside Japan and the Bundesliga, Sano’s name only really cut through during the 2026 World Cup. Since arriving in Germany in 2024-25, he has quietly become a mainstay for Mainz, racking up 84 appearances in all competitions, 80 of them as a defensive midfielder.

Last season he finally added end product to his game, contributing seven goals in the 2025-26 campaign. That output, from the base of midfield, will not have gone unnoticed by a data-driven recruitment team.

Drop him into Liverpool’s engine room and the picture becomes intriguing. Sano’s presence would put immediate pressure on Ryan Gravenberch for minutes in the deeper roles. He brings discipline, positional awareness and a platform for the more expressive midfielders to roam, the kind of balance Iraola will crave if he wants to unleash his attacking patterns without leaving the back line exposed.

Yet even a £50 million signing cannot fix everything.

Sano does nothing for the club’s homegrown quota. If Jones departs on top of other British or Irish exits, Liverpool will still need another midfielder trained in England or Wales just to meet registration rules. In pure squad-building terms, that means Sano would be one piece of a larger puzzle, not the definitive answer.

Time, money and a test of ambition

So Liverpool stand at an awkward crossroads. They have a new head coach, a restless fanbase and a squad that feels lighter than it should with just over a month of the window left.

Mainz have set their terms. Sano is not on the market unless someone pays to take their breath away.

Now the question hangs over Anfield: are Liverpool prepared to do exactly that for a defensive midfielder from Mainz, while other fires still burn across the squad? Or will they blink, and watch another target slip away as the season rushes into view?
