The summer transfer window is football's equivalent of a high-stakes poker game: clubs bluff, bid, and sometimes walk away with a jackpot. In July 2026, Manchester United triggered a £35m release clause for Belgium midfielder Youri Tielemans, while Manchester City gazumped Arsenal to sign 17-year-old winger Jeremy Monga for £10m plus add-ons. These moves are the latest examples of how Premier League clubs use the off-season to reshape their squads.
At its simplest, a transfer is a deal between two clubs to move a player from one to the other. The buying club pays a fee to the selling club, and the player agrees a new contract. Tielemans, 29, joined Manchester United from Aston Villa on a five-year deal after United paid his release clause—a predetermined amount set in his contract that allows any club to buy him without Villa's permission. Tielemans had spent three seasons at Villa after joining Leicester City in 2019. He scored Villa's opening goal in the Europa League final win over Freiburg in May 2026 and has 90 caps for Belgium.

Meanwhile, Manchester City's signing of Jeremy Monga from Leicester City illustrates the battle for young talent. Monga, who turned 17 on the day of the transfer, had agreed a professional contract with Leicester that triggered a transfer fee. City paid £10m plus add-ons, beating Arsenal and Brentford to the winger. Premier League clubs often invest heavily in teenagers: Tottenham spent £30m on 18-year-old Archie Gray in 2024, and Manchester United paid £27m for 18-year-old Luke Shaw in 2014.
Why do clubs need to rebuild every summer? Players leave on free transfers when their contracts expire, as Casemiro did at Manchester United. Injuries also force changes: United targeted Tielemans after midfielder Manuel Ugarte suffered a knee injury at the World Cup. Clubs also use data to identify targets: United's director of football Jason Wilcox praised Tielemans' "consistency" and "technical qualities," while City's new manager Enzo Maresca had worked with Monga at Leicester.
For UK readers, these transfers shape the Premier League's competitiveness. Manchester United have now signed Tielemans, Andrey Santos (£48m from Chelsea), and goalkeeper Karl Darlow, signalling a push for the "biggest trophies," as Tielemans said. City's capture of Monga weakens a rival (Leicester were relegated) and strengthens their own academy-to-first-team pathway, which has produced players like Phil Foden. Arsenal, who led the race for Monga, will need to find other targets. The transfer window runs until the end of August, so more deals are expected.
Q: What is a release clause? A release clause is a fixed transfer fee written into a player's contract. If another club pays that amount, the selling club must allow the player to negotiate terms. Tielemans' £35m release clause was activated by Manchester United, meaning Aston Villa could not block the move.
Q: How do add-ons work in transfers? Add-ons are extra payments triggered by performance milestones, such as appearances, goals, or team success. Monga's deal includes add-ons on top of the £10m initial fee. They allow clubs to spread the cost and share risk.
Q: Why do clubs pay large fees for teenagers? Clubs invest in young players because they can develop into stars worth much more. Monga had already made 37 senior appearances for Leicester, including seven in the Premier League. Early investment can yield long-term rewards, as seen with Foden at City.
What happens next? Manchester United may pause further signings after adding two midfielders, though Atalanta's Ederson remains a target. City will continue to build their squad under Maresca. Arsenal, after missing out on Monga, must decide whether to pursue alternative young talents or experienced players. The transfer window closes on 1 September 2026, leaving clubs about six weeks to complete their business.
