Chelsea secured a 3-1 pre-season victory over Real Sociedad, with manager Xabi Alonso’s 3-4-3 formation demonstrating its efficacy ahead of the Premier League opener against Fulham. The system, which Alonso used for the third match, was a key focus as the club prepared for the 2026–27 campaign. Morgan Rogers, the £117m signing from Aston Villa, scored just 10 minutes into his debut, while João Pedro netted twice to seal the win [1].
Chelsea 3-1 Real Sociedad: Alonso’s 3-4-3 System Proves Effective in Pre-Season
Formation Flexibility and Tactical Adjustments
Alonso’s decision to deploy a 3-4-3 system marked a shift from the 4-2-3-1 he used in Chelsea’s first three pre-season games. The back three—Wesley Fofana, Maxence Lacroix, and Levi Colwill—proved adaptable, with Lacroix excelling in the center-back role. The formation’s fluidity allowed Moisés Caicedo to drop into defense and Wesley Fofana to operate wide on the right, creating a dynamic structure that mirrored Alonso’s success at Bayer Leverkusen in 2024 [1]. However, the system faced challenges in the first half, with Chelsea struggling to press and cover space, leading to Real Sociedad’s equalizer by Jon Aramburu. The Blues improved after halftime, with João Pedro’s two goals highlighting the formation’s potential [3].
Key Performances and Transfer Context
Morgan Rogers’ goal in his debut underscored his immediate impact, though his £116m move from Aston Villa was delayed by the World Cup. João Pedro, meanwhile, continued his prolific pre-season form, scoring twice and contributing to Chelsea’s attacking rhythm. His performance has fueled speculation about his future, as exit rumors persist [4]. The match also saw Enzo Fernández receive a mixed reception, with fans booing and cheering him during his appearance. The Argentina midfielder’s reaction followed his recent transfer links to Manchester City, though the boos reportedly lessened as the game progressed [1].
Transfer Activity and Squad Depth
Chelsea’s squad featured several summer signings, including Rogers and Maxence Lacroix, while others like Tosin Adarabioyo, Liam Delap, and Nicolas Jackson were omitted from the matchday roster. No official reasons were given for their absence, though transfer speculation surrounds the trio. Meanwhile, winger Mykhailo Mudryk and midfielder Pedro Neto are under pressure to secure their places, with Neto contributing as a wingback in the 3-4-3 system [1]. Alonso’s ability to rotate players suggests a competitive race for starting positions as the Premier League season approaches [3].
Looking Ahead: Alonso’s Vision for the Season
With the Premier League opener against Fulham just eight days away, Alonso’s preference for the 3-4-3 system signals his tactical priorities. The formation’s adaptability and the performances of players like João Pedro and Rogers offer optimism, though challenges remain in the first half. Real Sociedad’s ability to exploit gaps in Chelsea’s defense highlights areas for improvement. As the Blues prepare for the 2026–27 campaign, the 3-4-3 system will be a central focus in determining their competitiveness against rivals like Fulham and Manchester City [2].
