Chelsea’s decision to bring Emiliano Martínez to Stamford Bridge has already sparked debate, with former Manchester United captain and football pundit Roy Keane questioning whether the Argentine goalkeeper is the right man to solve the Blues’ long-standing problems between the posts.

Chelsea officially completed the signing of Martínez from Aston Villa on a three-year contract, with the reported transfer fee around £7.5 million. The move came after Chelsea identified the goalkeeper position as an area that needed strengthening.

However, while some former players have welcomed the transfer, Keane is far from convinced.

🗣️ Roy Keane delivers blunt verdict on Martínez

Speaking about Chelsea’s new goalkeeper, Keane questioned whether the move represents a significant upgrade for Xabi Alonso’s side.

“I don’t know if that’s a great signing for Chelsea.”

Keane acknowledged that Chelsea needed a new goalkeeper but immediately raised concerns about Martínez’s performances for Aston Villa last season.

The former Manchester United midfielder also pointed to a particular weakness he believes could cause Chelsea problems.

“He loves parrying saves straight into the six-yard box.”

Keane’s comments have quickly generated debate among Chelsea supporters, especially because Martínez arrives at Stamford Bridge with an impressive reputation and a long list of major achievements.

🧤 Why did Chelsea sign Emiliano Martínez?

Chelsea’s decision to sign Martínez was largely influenced by the club’s desire for greater experience and competition in goal.

The 33-year-old goalkeeper has spent the past six seasons at Aston Villa, making 256 appearances for the club and establishing himself as one of the Premier League’s most recognizable goalkeepers. He also played a key role in Villa’s recent success, including their Europa League triumph.

At international level, Martínez has an even more impressive résumé.

He was Argentina’s goalkeeper during their 2022 FIFA World Cup triumph and has also won the Copa América twice. He has additionally won the Yashin Trophy twice, recognition that underlines his status as one of the world’s leading goalkeepers during his peak years.

So, on paper, Chelsea are not signing an inexperienced goalkeeper.

They are bringing in a goalkeeper who has played at the highest level, won major international trophies and experienced the pressure of playing important matches.

🔵 Chelsea needed experience in goal

The timing of Martínez’s arrival is also significant.

Chelsea’s goalkeeping situation had come under scrutiny following inconsistent performances from Robert Sánchez. The club subsequently moved quickly to strengthen the position, with Xabi Alonso identifying a goalkeeper as a priority.

Martínez therefore arrives with a clear opportunity.

He does not necessarily have to convince everyone immediately that he is the best goalkeeper in the Premier League. His first task is to bring stability, leadership and experience to a Chelsea team undergoing another major transformation under Alonso.

That could be particularly important for a squad containing several young players.

👀 Roy Keane vs the Martínez believers

Interestingly, Keane’s assessment is not shared by everyone.

Former Arsenal striker Ian Wright has reportedly described Martínez as a great signing for Chelsea and believes the Argentine has the ability to take the Blues to another level.

That creates an interesting debate.

Is Martínez an experienced goalkeeper capable of immediately improving Chelsea?

Or does Keane have a point about the goals Chelsea could concede if Martínez repeats some of the mistakes he made at Aston Villa?

Those questions will ultimately be answered on the pitch.

💰 Is £7.5m a bargain for Chelsea?

Another major talking point is the reported transfer fee.

Chelsea reportedly paid around £7.5 million for Martínez, which is relatively modest for a goalkeeper with his experience and international pedigree.

From Chelsea’s perspective, the relatively low transfer fee could make the deal a calculated gamble.

If Martínez performs at his best, Chelsea could end up with an experienced goalkeeper at a very reasonable price.

But if his weaknesses become a regular problem, Keane’s concerns will suddenly look much more significant.

🔥 Martínez now has a chance to answer his critics

The biggest advantage Martínez has is that he can respond to criticism on the football pitch.

He has already dealt with enormous pressure during his career.

From winning the World Cup with Argentina to playing high-pressure Premier League matches for Aston Villa, Martínez has developed a reputation for being confident and highly competitive.

Chelsea will now expect that mentality to help them during difficult moments.

His personality could also become an important factor inside the dressing room. Martínez has never been shy about showing emotion, communicating with teammates or embracing pressure.

For a Chelsea side under Xabi Alonso, that leadership could prove valuable.

🎯 Can Emiliano Martínez take Chelsea to the next level?

That remains the big question.

Chelsea are building an ambitious squad under Alonso, and expectations are rising quickly. The club made several major additions during the 2026 summer transfer window, including Martínez, Morgan Rogers, Maxence Lacroix and other reinforcements.

The goalkeeper position is therefore more than just another squad decision.

If Chelsea want to challenge for major trophies, they need reliability at the back.

A goalkeeper can win points for a team, but mistakes can also cost points.

That is why Keane’s criticism has generated so much attention.

🗣️ Chelsea fans, what do you think?

Roy Keane has made his position clear.

He believes Chelsea may have taken a risk by signing Martínez and has questioned whether the goalkeeper is truly the solution to their problems.

But Martínez now has the perfect opportunity to answer him.

If the Argentine produces consistent performances, makes crucial saves and helps Chelsea keep more clean sheets, Keane’s doubts could quickly become a forgotten storyline.

If mistakes continue, however, the criticism will only become louder.
