England's 4-2 victory over Croatia in their World Cup opener served as an immediate statement of intent — and a clear signal of just how much Thomas Tuchel has reshaped the side since taking over from Gareth Southgate.

System first, stars second

The most striking shift under Tuchel is his willingness to leave high-profile names out of the squad entirely. At Euro 2024, Southgate selected Phil Foden, Cole Palmer, and Trent Alexander-Arnold as key figures. Tuchel left all three out of his World Cup squad.

The explanation lies in their contrasting philosophies. Tuchel defines his system first, then identifies players who fit the specific roles he needs — regardless of reputation. Southgate, by contrast, assembled the best individuals available and attempted to build a system around them, which at times meant fitting players into roles that did not entirely suit them.

That is why Morgan Rogers earned a place ahead of Foden and Palmer — Rogers is better suited to what Tuchel demands from the number 10 position. Without the through-balls of Alexander-Arnold, the long-range threat of Foden, or the creativity of Palmer, England may carry slightly less individual firepower. But Tuchel is betting that greater collective cohesion will more than compensate.

Speed through the middle third

Assistant coach Anthony Barry outlined the tactical thinking earlier this year, telling The Guardian that the team are focused on accelerating play through what he described as those crucial 24 metres in the central zone of the pitch — an area where, in his view, the game has become congested.

Against Croatia, that philosophy was visible from the first whistle. Goalkeeper Jordan Pickford recorded 72 touches as England deliberately played backwards, drawing Croatia forward before releasing runners in behind at pace. Southgate's sides, by comparison, built up more gradually — retaining possession and advancing as a unit before attempting to unlock deep defensive blocks.

Tuchel also instils specific patterns to dismantle opposition pressure. Against Croatia, as England recycled the ball, Declan Rice drifted wide left, Harry Kane dropped into the space Rice vacated, and Jude Bellingham pushed into the final line. These movements broke Croatia's press and created the angles for direct passes into Bellingham, Anthony Gordon, and Noni Madueke.

A greater appetite for risk

Southgate's great strength was managing variance — keeping matches tight and trusting England's quality to emerge in controlled conditions. The trade-off was a tendency to defend leads rather than extend them, most notably in the Euro 2020 final.

Tuchel accepts more exposure. England's substitutions against Croatia maintained the same attacking profile rather than adding defensive cover, and the side did look more vulnerable at the back than Southgate's teams. But the counter-argument is compelling: Bellingham's goal against Croatia grew out of a rehearsed attacking routine, not a moment of isolated individual brilliance — suggesting the system can generate match-winning moments without relying on a single superstar to improvise them.

Whether Tuchel's higher-risk approach pays off across a full World Cup campaign remains the central question surrounding England's tournament.
