There was a time, not so long ago, when full-backs were footballing afterthoughts. Defenders who stayed home, kept things tidy, and rarely troubled the opposition box. That time is gone. The position has undergone a revolution so thorough that the best right back in Premier League history might now be judged more on assists than tackles. Full-backs have become elite engines, combining the speed of wingers with the vision of playmakers, and the transformation tells us something broader about where the game is heading. For context on how the league’s pace in modern football has shifted, consider that historical fastest players data from the fastest players in Premier League history shows a surge in extreme speedsters that would have seemed impossible during the Theo Walcott era.

The Timeline Nobody Saw Coming

Back in 2011/12, only five full-backs across the entire Premier League created 20 or more chances in a season. Five. The position existed in a defensive box, and most managers saw it that way. Width came from touchline-hugging wingers. Full-backs covered for them, tracked runners, and generally tried not to get noticed.

By 2015/16, that number had exploded to 21. Something fundamental had changed, and it wasn’t subtle. Tactics pioneered years earlier, think Fabio Capello unleashing Roberto Carlos at Real Madrid, had finally filtered down into standard Premier League thinking. Overlapping runs became default. Teams started relying on full-backs to provide the width that wingers once monopolized. Goals per game climbed to a record of roughly three, and the full-back evolution was a significant reason why.

The shift didn’t stop there. By the 2020s, full-backs were no longer just overlapping; they were integral to build-up play itself. Manchester City’s sequences, for instance, involved their full-backs in 64.1% of possessions. These weren’t auxiliary players anymore. They were the system.

What drove this? Partly necessity. As teams packed central midfield zones, space migrated to the flanks. Partly ambition. Managers realized that a full-back who could cross, dribble, and pick a pass was essentially a free attacking player, one the opposition’s structure wasn’t designed to account for. The position split into distinct profiles: defensive full-backs, attacking full-backs, and genuine playmakers operating from deep wide positions. All of them needed the stamina to cover the pitch end to end, every single match.

Liverpool’s Laboratory

Nowhere has this transformation been more visible than at Anfield. Trent Alexander-Arnold and Andy Robertson didn’t just benefit from the full-back revolution; they became its poster children. The pair feature in 61.5% of Liverpool’s open-play sequences and create 35% of the team’s chances. Those numbers are staggering for players nominally classified as defenders.

Liverpool’s corner-kick data is equally telling. A remarkable 94.1% of their corners are delivered by full-backs, predominantly outswingers. Alexander-Arnold, in particular, has redefined what the best right back in Premier League conversations even look like. His passing range belongs in a number ten’s highlight reel.

Antonio Conte’s arrival at Chelsea offered another case study. His 3-4-3 system turned wing-backs into the primary creative outlets, demanding players like Marcos Alonso and Victor Moses cover enormous ground while contributing at both ends. It worked spectacularly, winning a title, and further cemented the idea that wide defenders could be a team’s most dangerous weapons.

The ripple effects spread everywhere. Suddenly every club wanted full-backs who could do everything. Transfer fees ballooned. Scouting profiles changed. Youth academies started coaching their wide defenders to receive in half-spaces and play inverted passes. The position had been completely reimagined.

Speed Changed Everything

You cannot separate this evolution from raw pace. The fastest player in EPL discussions used to center on a handful of outliers. Now the league overflows with players who can hit extraordinary top speeds, and many of them are full-backs. Kyle Walker spent years as arguably the quickest defender in world football. Achraf Hakimi, Alphonso Davies, and others followed the template globally.

This matters because full-backs must now match the pace of the wingers they face while also having the gas to bomb forward and support attacks. The physical toll is enormous. Covering 11 or 12 kilometers per match, with significant portions at high intensity, has become standard for modern full-backs. Careers at the top level in this position burn shorter and hotter than they used to.

And the pace increase hasn’t just taxed players. Data by TipsGG confirms that match speeds and sprint volumes have risen consistently across the league, creating a cascade of consequences that extends well beyond the pitch’s 22 outfield participants.

The Officials Running Alongside

There is an overlooked side effect to this relentless modern pace: the referees actually have to keep up. Every time an elite full-back turns on the jets for a counterattack, the official is forced to sprint right alongside them just to spot a potential foul. They are logging the exact same 10 to 12 kilometers a match as the players, just without the glory of touching the ball. You would almost think they should be charging by the kilometer, or at least demanding a special cardio bonus for trying to outrun modern wingers.

We actually covered the financial side of this a while back. Our previous breakdown of Premier League referee salary structures looks into exactly how much do Premier League referees get paid for surviving these weekly track meets. Spoiler: they do just fine for themselves, even without the sprinting bonus.

Where This Goes Next

The full-back position will keep evolving. Inverted full-backs, players who tuck inside to become midfielders during possession, are already common under coaches like Pep Guardiola. The next generation will likely blur positional lines even further, creating hybrid roles that would be unrecognizable to defenders from 15 years ago.

Who is the fastest player in the Premier League matters now partly because it determines which full-backs can survive at the highest level. Speed is the entry requirement. Everything else, crossing, playmaking, defensive intelligence, gets layered on top.

The question nobody seems to be asking is whether the people officiating this faster, more complex game deserve a proportional upgrade in recognition and pay. Full-backs evolved because the sport demanded it. Officials face the same demands with far less reward. Something about that feels unfinished.
