Why Chelsea need more than a new goalkeeper to be title challengers
August 30, 2026 17:12
Chelsea completed the signing of Emiliano Martínez from Aston Villa and handed him a debut at Stamford Bridge within hours of the club confirming the transfer. Martínez started in the 4-3 win over Brighton after having trained with the squad only briefly before the game; he conceded three goals but was not widely blamed for them.
The victory left Chelsea with two wins from two league matches, but the back-to-back conceding of five goals (three against Brighton, two at Fulham) underlined ongoing defensive frailties. Manager Xabi Alonso had chosen Martínez ahead of Robert Sánchez for the Brighton match; Sánchez had been at fault for at least one of the goals in the previous fixture.
KEY CONTEXT
- Martínez joined Chelsea for a reported fee of £7.5m and had signed after helping Argentina to the 2022 World Cup and Aston Villa to the Europa League in May; he is a two-time Fifa Best Goalkeeper winner.
- Sánchez arrived at Chelsea from Brighton for around £25m in 2023 and had been backed by club staff and the head of goalkeeping, Ben Roberts, but has shown a tendency to costly errors in the 2024–25 season and briefly lost his place earlier this year.
- Despite Martínez having made more errors leading to goals during his time at Villa than Sánchez did last season, Martínez’s underlying shot-stopping and passing metrics were stronger.
WHY IT MATTERS
Martínez’s arrival addresses Chelsea’s need for an experienced, high-profile goalkeeper, but the few early matches show that upgrading the goalkeeper alone has not fixed the team’s defensive issues. Chelsea’s potent attacking trio has delivered wins, yet conceding multiple goals in successive games suggests the club must improve defensive control if Alonso wants the side to compete for top honours.
WHAT TO WATCH NEXT
- How Martínez settles into the squad with a full week of preparation before Chelsea’s trip to Arsenal.
- The club’s decision on Robert Sánchez’s future: he is reportedly available for transfer and has dropped in the pecking order, but the manager has said the situation will be reviewed.
- Whether Alonso can adjust tactics or personnel to reduce the number of goals conceded and produce more controlled performances.
KEY FACTS
- Martínez signed from Aston Villa for about £7.5m and debuted for Chelsea in a 4-3 win over Brighton.
- Chelsea have conceded five goals across their first two league games this season.
- Martínez is a two-time Fifa Best Goalkeeper winner and helped Argentina win the 2022 World Cup; he also won the Europa League with Villa in May.
