A long-term answer in defence?

Chelsea remain in the market for a centre-back following the departures of Antonio Rüdiger and Thiago Silva, and Jérémy Jacquet has been identified as a potential solution. At just 20 years old, the Rennes defender is far from the finished product, but he fits the BlueCo profile: elite upside, high ceiling and long-term value.

Unlike experienced names who have already logged major minutes at Stamford Bridge, Jacquet is still developing. Yet that is precisely the appeal. Rather than repeatedly spending around €20m on young players who rarely reach the first team, Jacquet represents the kind of top-tier prospect worth backing fully.

So who exactly is he, why have Chelsea zeroed in on him, and is he really worth the €70m Rennes are demanding?

Where it all began

Born on July 13, 2005, in Bondy, a suburb of Paris, Jacquet grew up surrounded by football. He was just one year old when Zinedine Zidane’s infamous headbutt dominated the 2006 World Cup final. By the time France lifted the trophy again in 2018, Jacquet was already playing locally with RC Joinville, taking his first steps in the game.

His path also highlighted a familiar issue in French football: Paris Saint-Germain’s failure to retain top local talent. In 2019, Jacquet signed an amateur deal with Rennes, a club renowned for developing young players and providing them with real first-team pathways.

The breakthrough

At 18, Jacquet made the leap from Rennes’ youth setup to the senior side, making his Ligue 1 debut in January 2024 against Nice. Soon after, he was loaned to Clermont, who were battling relegation. Although the club eventually went down, the move proved crucial for his development.

His performances, combined with a standout summer at the UEFA U19 European Championship, where France reached the final, made it clear that Ligue 2 was too small a stage. Rennes recalled him midway through the 2024–25 season, paying €900,000 to terminate the loan.

Jacquet went on to start 11 of Rennes’ final 14 league matches, helping them pull clear of relegation trouble and finish comfortably in mid-table.

Momentum building

Despite limited top-flight experience, Jacquet was already attracting serious interest in 2025. Arsenal explored a move as a potential replacement for Jakub Kiwior, but Rennes shut the door quickly after tying the defender to a new deal in May. The Gunners ultimately turned to Piero Hincapié.

Jacquet remained unfazed. This season, he has started every league match for Rennes when available, missing only two through suspension. He has also earned five caps with France’s U21s, with growing calls for Didier Deschamps to consider him for the senior side ahead of this summer’s World Cup.

With that trajectory, it was inevitable that January would bring renewed transfer noise. Chelsea may be leading the chase, but they are far from alone in their admiration.

Key strengths

Combining composure with controlled aggression, Jacquet has the physical and mental traits to become an elite centre-back. He is comfortable in both a back three and a back four, capable of operating on either side or even stepping into a sweeper role.

Out wide in a three-man defence, his recovery pace allows him to cover large spaces. Centrally, he excels in the air, a quality that would add another weapon to Chelsea’s already strong set-piece threat.

His positional intelligence stands out. Jacquet ranks in the 95th percentile for interceptions among European centre-backs, averaging 1.69 per 90 minutes, reflecting both his anticipation and willingness to step in early. On the ball, he is equally impressive, regularly switching play, breaking lines with vertical passes and carrying the ball into midfield.

Areas to refine

Two main concerns follow Jacquet. The first is adaptation. Thriving in Ligue 1 does not guarantee success in the Premier League, especially under the intense scrutiny that comes with being labelled Chelsea’s long-term defensive answer.

The second is discipline. His aggressive style usually works in his favour, but when it goes wrong, it can be costly. Lapses in concentration have led to unnecessary fouls and bookings, including his first red card earlier this season in a heavy defeat to PSG.

Joining a side that currently sits bottom of the Premier League fair-play table would only magnify that challenge.

The Cristian Romero comparison

It may disappoint some Chelsea fans, but Jacquet’s closest stylistic comparison is Tottenham’s Cristian Romero. Like the Argentine, Jacquet plays on the edge, thriving on confrontation and confidence. When it clicks, the blend of aggression and technical quality is devastating.

Romero remains vital to Spurs’ build-up play despite defensive inconsistencies, and that dual threat is something Chelsea believe Jacquet can replicate. Crucially, at just 20, he has time to iron out the rough edges that have limited Romero’s evolution.

What comes next?

Chelsea have already agreed personal terms with Jacquet, and the defender is open to the move. Whether Rennes’ €70m asking price proves negotiable remains to be seen, but confidence is high in west London that he is worth the investment.

Rennes, sitting just two points off the Champions League places, know interest will only grow if they hold firm. Head coach Habib Beye has made their stance clear, calling Jacquet “essential” to the club’s ambitions.

For Chelsea, the need is urgent. If they truly believe in Jacquet’s talent, history suggests one thing is certain: every player has a price.
