For Liverpool, this is no ordinary summer run-out. The schedule is narrowing, the opening weekend is getting closer, and places are still there to be claimed before the Premier League return.
That early return points to intent. Munoz appears determined to fast-track his adaptation rather than ease his way into the group.
That is the key question, and Munoz did little to play it down. "Obviously if the coach says so after training and asks me to feature in the starting XI, I'll be there," he said. "I'm keen and I can't wait to get started. [Against] Monaco, why not?"
There is a practical football case for using him, too. He was part of Spain's winning squad, but his tournament involvement was limited after a minor injury, so he does not appear to be carrying the same heavy recent load as some internationals.
The decision now rests with Iraola. He must weigh rhythm against risk, and excitement against conditioning. Throwing Munoz in from the start may be a step too soon, but a cameo would make plenty of sense if training has gone smoothly.
Either way, Liverpool's final pre-season stretch is taking shape. With a league opener away to Newcastle on 23 August, the next storyline is obvious: whether Munoz can turn readiness into a real role before the serious business begins.
