Walker reveals Pochettino's brutal Gacon test — and why only Dele Alli ever completed it

Kyle Walker has revealed the details of Mauricio Pochettino’s notorious ‘Gacon’ fitness test, describing Dele Alli as the only Tottenham Hotspur player he ever witnessed complete it — and warning that Manchester United’s squad can expect the same treatment when the Argentine takes charge at Old Trafford.

Speaking on The Overlap, Walker broke down the mechanics of the drill that became a defining feature of Pochettino’s tenure at Spurs following his arrival from Southampton in 2014. “We had the famous thing called the Gacon — whoever played for Tottenham will know the Gacon,” Walker said. “It starts at 145 metres and you have 45 seconds to get there, you then walk up five metres to another cone and have to run back. It’s a continuous thing and there were 16 or 17 cones.”

“The only person that I’ve ever seen complete it was Dele Alli — he was an animal at running.”

Alli’s extraordinary stamina was central to Pochettino’s high-pressing blueprint at White Hart Lane through the mid-to-late 2010s. Operating as the energetic attacking midfielder behind Harry Kane, Alli consistently covered more ground than almost any other player in the squad, driving Tottenham’s counter-press and contributing to back-to-back Premier League title challenges in 2016 and 2017.

The relentless physical demands of Pochettino’s methods set a clear standard for what it took to succeed at Spurs — a standard that Walker says hit him hard when he made his £50 million move to Manchester City in the summer of 2017. The contrast with Pep Guardiola’s pre-season approach was immediate and jarring.

Where Pochettino had built his teams around endurance and off-the-ball running, Guardiola’s sessions revolved almost entirely around possession drills, with some of City’s senior players visibly relaxed in training. Walker singled out Sergio Agüero as a case in point.

“I remember getting off in the pre-season and you’ve got Kun Agüero who’s just balling around training — bad trainer, bad trainer, but he turned it on in the game,” Walker said. “I got back to my hotel room after and speaking to my dad saying, ‘I think I’ve made a mistake here.’ I went from a Pochettino team of running hard and we’re going to run all over you, to looking now and thinking we’re doing hardly any running in pre-season because Pep doesn’t like running.”

Walker’s account offers a vivid preview of what Pochettino is likely to demand from United’s players once he is installed at Old Trafford — a fitness-first culture that left a lasting impression on everyone who experienced it, and that produced one of the Premier League’s most physically dominant sides of the last decade.
