Tuchel's words of warning still echoing in the Three Lions' ears as they prepare to take on defensive DR Congo in the World Cup last 32 - a battle that promises to be as gruelling as it is crucial. The German gaffer knows his team will have to dig deep, relying on mental toughness and collective spirit to overcome an opponent built for solidity rather than flair.
And Tuchel isn't naive to the challenge at hand, drawing parallels with group stage foes Ghana and Panama - opponents who made life difficult with their 'park-the-bus' tactics. "We're not getting full praise just yet," he said bluntly. "Every one of us expects to win, every one of you expects us to win, every one of the fans expects us to win - so we're just matching our own expectations at this stage." Breaking down that low block can be a slog, draining and nerve-wracking.
But Tuchel's message is clear: no room for doubt or panic. "We keep believing, we do our things," he urged his players. "Encourage each other because there's commitment and togetherness." England know they've been in these situations before - drawing with Ghana and taking 62 minutes to score against Panama. Now it's time to put in the hard yards and reap the rewards.
Selection headaches abound for Tuchel, with decisions pending on the backline following injuries to Reece James and Jarell Quansah. Djed Spence is set to step into right-back duties, while Declan Rice returns to midfield and Marcus Rashford eyes a repeat start on the left wing. The Bukayo Saka conundrum remains - can he overcome his Achilles problem for a second consecutive match?
Tuchel's revealed some of his own superstitions too - but that's as far as we'll go, leaving him to keep those lucky charms under wraps. Preparation for a potential penalty shootout has been underway, and while the squad may not be thrilled at the prospect, they know it's all part of the knockout football package.
And so England's focus remains on securing that first win in Atlanta - a task that will require toil and effort despite being overwhelming favourites. "The less glamorous stages come first," Tuchel reminded them, likening these opening rounds to FA Cup ties - necessary hurdles to overcome before the glamour of the later stages kicks in.
