Arsenal's Pablo Marí said he felt "lucky" to escape life-threatening injuries after being stabbed and seeing "a person die in front of me" in an Italian supermarket.

Milan's Niguarda hospital performed surgery to reconstruct two injured muscles in Marí's back.

Italy's Carabinieri police said a 47-year-old supermarket employee was killed in Thursday's attack.

Another employee was left injured along with four customers, including Marí.

The 29-year-old, who is on loan at Monza from Arsenal, had been walking around the supermarket with his wife and son when he was stabbed in the back, reports Gazzetta dello Sport

Monza said Marí's surgery went well, adding that he will remain in hospital for two or three days before starting the rehabilitation process.

"This type of muscle injury usually requires two months of rest before one can resume physical activities," the club said in a statement.

Italian outlet Corriere della Sera reported that former Napoli player Massimo Tarantino was among those who immobilised and disarmed the attacker before police arrived.

"I'm not a hero. I didn't do anything special," said 51-year-old Tarantino.

Monza chief executive Adriano Galliani said the club have asked the Italian football league to postpone Monday's Serie A match at home to Bologna scheduled for Monday because the team is "in a total state of shock".

"I'm happy with the outcome of the surgery, but we asked to postpone the next league game," Galliani told Gazzetta.

"Last night our players were crying. The boys are in shock. We do not know if our request will be accepted or not."

Marí joined Arsenal from Brazilian side Flamengo in January 2020 and played 19 times for the Gunners before joining Udinese on loan at the start of the year.

He was then loaned to newly promoted Monza in August.
