Erling Haaland and Mohamed Salah are among the Premier League stars "addicted" to chess, helping to spark a surge in the game's popularity among younger people.
Manchester City striker Haaland is so fascinated by the game that he recently invested in a ground-breaking new chess tour to capitalise on the increased profile bestowed by its celebrity players.
As well as Haaland, Liverpool forward Salah and England team-mates Harry Kane, Trent Alexander-Arnold and Anthony Gordon are all avid chess players.
Salah is obsessed by playing the faster 'blitz' version of chess using an anonymous online profile.
"I'm addicted to chess. Every day, literally every day," the Egyptian said.
Arsenal midfielders Martin Odegaard and Eberechi Eze are both keen players, with the latter winning an amateur tournament in 2025.
Chess grandmaster Magnus Carlsen, a five-time world champion, is a huge football fan and the Norwegian's love for both games has played a role in the surprise crossover.
Alexander-Arnold often plays chess with his brothers and once levelled-up to face Carlsen, who defeated the Real Madrid defender in a 17-move rout that lasted just five minutes.
AC Milan winger Christian Pulisic has the queen chess piece tattooed on his arm in tribute to his grandfather, who taught him the game as a child.
France World Cup winner Antoine Griezmann and Real Madrid's Dani Carvajal are also aficionados.
On the surface, the contemplative, cerebral nature of chess is a stark contrast to the physicality and aggression of football.
But dig deeper and there are more similarities than you would expect.
"Chess is an incredible game. It sharpens your mind, and there are clear similarities to football," Haaland said.
"You have to think quickly, trust your instincts, and think several moves ahead. Strategy and planning are everything."
'IT'S REMARKABLY SIMILAR'
Backed by the International Chess Federation (FIDE), the new tour will feature four tournaments each year in different cities, with a world champion crowned across three disciplines – fast classic, rapid and blitz.
Each season will have a minimum prize pool of £2 million ($2.7 million).
"Seeing a world-class athlete like Erling Haaland join the Total World Chess Championship Tour is a powerful signal of the global attention and cultural relevance that chess enjoys today," FIDE president Arkady Dvorkovich said.
Chess has its roots in seventh century India.
But those humble origins are a far cry from the technology fast-tracking the chess boom, with online apps taking over from the traditional board as the game's most common battleground.
Online play rocketed during the Covid-19 pandemic and, according to FIDE, at least 1.5 billion people now have a chess app on their phone.
Netflix series "The Queen's Gambit" and the impact of celebrity influencers, including footballers, have all contributed to the boom transforming the previously staid image of chess.
The strategy involved in chess also appeals to football managers looking for a mental edge in their tactical battles on the pitch.
Quoted in the book 'Pep Confidential', Manchester City boss Pep Guardiola said: "You have no idea how similar the two things are."
Avid Real Madrid fan Carlsen sees his game through the same lens as former Barcelona coach Guardiola: "In chess and football, the important thing is to control the middle. If you control the middle, you control the pitch or the board," he said. "In terms of space, it's remarkably similar."
But will the satisfaction of a successful checkmate ever replace the thrill of scoring a winning goal for chess-fixated footballers?
For Kane, his true love remains football, leaving chess as the perfect way to relax.
"I use chess to switch off," he said. "It's such a mental game. You have to focus on every moment."
