Endo’s Liverpool career has moved sharply from the role he occupied under Jürgen Klopp. The report says he made 43 appearances and started 34 matches during Klopp’s final cycle, but began only 10 games under Slot, including just three in the Premier League.
That contrast captures the problem. Endo has remained useful as a late-game shield, entering to protect narrow leads and close spaces, but he has rarely been trusted to shape matches from the start. A new manager may view that experience differently.
The reported ankle injury that disrupted Endo’s previous campaign adds another layer of uncertainty. His return came late, and he was subsequently left out of Japan’s final World Cup squad after concerns over his physical readiness, the report says.
His decision to retire from international football would nevertheless remove a significant demand from his calendar. At 33, Endo may benefit from uninterrupted training time and a clearer focus on Liverpool, particularly during a preseason in which squad absences could create opportunities.
The question for Iraola will be whether Endo offers enough beyond defensive protection. His reading of danger, discipline and leadership remain valuable, but Liverpool’s midfield also requires speed in circulation and the ability to resist pressure. Endo must show he can contribute before the final stages of matches.
With his contract reportedly entering its final year, this is more than another preseason. The first fixtures under Iraola should reveal whether Endo is viewed as a specialist or a genuine squad option-and whether a reduced international burden can revive his Anfield career.
