In the past, the England assistant coach was playing at a lower division club. Today, his attention is fixed on helping the head coach secure World Cup glory in 2026. His journey from player to coach began through volunteering for Accrington's Under-16s. He remembers, “It was in the evenings, third of a pitch, asked to do 11 v 11 … flat balls, not enough bibs,” and he was hooked. He realized his purpose.
His advancement is incredible. Beginning as Paul Cook’s assistant, he built a standing for innovative drills and great man-management. His club career included elite sides, and he held coaching jobs abroad across multiple countries. He's coached stars like world-class talents. Today, as part of Team England, it's all-consuming, the “pinnacle” as he describes it.
“Everything starts with a dream … But I’m a believer that passion overcomes challenges. You dream big but then you bring it down: ‘How do we do it, gradually?’ We aim for World Cup victory. Yet dreams alone aren't enough. We have to build a structured plan that allows us to maximize our opportunities.”
Obsession, especially with the smallest details, is central to his philosophy. Working every hour under the sun—sometimes the moon, too, he and Tuchel push hard at comfort zones. Their strategies include psychological profiling, a plan for hot conditions for the World Cup in the US, Canada, and Mexico, and building a true team. He stresses “Team England” and avoids language like “international break”.
“You’re not coming here for a holiday or a break,” he explains. “It was vital to establish a setup that the players want to be part of and they're pushed that going back is a relief.”
The assistant coach says and the head coach as “very greedy”. “Our goal is to master all parts of the match,” he states. “We strive to own every metre of the pitch and we dedicate many of our days on. It’s our job not just to keep up with developments and to lead and create our own ones. This is continuous with a mindset of solving issues. And to clarify complicated matters.
“We get 50 days with the players ahead of the tournament. We need to execute an intricate approach for a tactical edge and explain it thoroughly in that period. It's about moving it from idea to information to knowledge to execution.
“To build a methodology for effective use in the 50 days, we must utilize the entire 500 days we'll have from when we started. When the squad is away, we need to foster connections with them. We must dedicate moments on the phone with them, we need to watch them play, understand them, connect with them. If we limit ourselves to that time, it's impossible.”
The coach is focusing on the last two in the qualifying campaign – versus Serbia in London and in Albania. The team has secured a spot in the tournament by winning all six games with perfect defensive records. Yet, no let-up is planned; quite the opposite. Now is the moment to strengthen the squad's character, for further momentum.
“We are both certain that our playing approach must reflect everything that is good about the Premier League,” Barry explains. “The physicality, the flexibility, the strength, the work ethic. The national team shirt should be harder than ever to get yet easy to carry. It ought to be like a superhero's cape not protective gear.
“To ensure it's effortless, it's crucial to offer a style that allows them to play freely similar to weekly matches, that resonates with them and encourages attacking play. They must be stuck less in thinking and focus more on action.
“There are emotional wins you can get as a coach at both ends of the pitch – starting moves deep, closing down early. Yet, in the central zone of the pitch, those 24 metres, we feel the game has become stuck, particularly in the Premier League. Coaches have extensive data these days. They understand tactics – mid-blocks, deep blocks. Our aim is to increase tempo in that central area.”
Barry’s hunger for development is relentless. When he studied for the top coaching badge, he felt anxious regarding the final talk, especially as his class included stars including former players. For self-improvement, he went into difficult settings he could find to hone his presentations. One was HMP Walton locally, where he also took inmates during an exercise.
He earned his license as the best in his year, and his research paper – focusing on set-pieces, where he studied numerous set-plays – became a published work. Frank was one of those convinced and he brought Barry on to his staff at Chelsea. When Lampard was sacked, it said plenty that the team dismissed most of his staff except Barry.
The next manager at Stamford Bridge was Tuchel, and shortly after, he and Barry won the Champions League. When Tuchel was dismissed, the coach continued with Potter. Once Tuchel resurfaced with Bayern, he got Barry out from Chelsea to rejoin him. English football's governing body consider them a duo akin to Gareth Southgate and Steve Holland.
