Federico Chiesa has vowed to make an impact for Juventus after a "horrible year" that saw him sidelined with a long-term injury.

The Italy international scored the winner in a 2-1 Coppa Italia victory against Monza on Thursday, his first goal in 378 days after rupturing his anterior cruciate ligament 12 months ago.

Juventus have endured a turbulent spell in Chiesa's absence, ceding their Serie A crown to Milan and finding themselves adrift of runaway leaders Napoli this time around, as well as exiting the Champions League in the group stage.

Like the Bianconeri, Chiesa has a point to prove on his return and is pushing to aid his colleagues after being helpless amid their struggles in the past year.

"It has been a horrible year for me. I am now focusing on training and getting back into shape," he told Sport Mediaset.

"Let's say I need to get really into shape, getting used to playing every three days. I was not used to it, but I am trying to give my all to help my teammates, seeing as I was unable to help them for a year."

Chiesa's goal gave Juve a much-needed victory following a 5-1 drubbing at the hands of Napoli last time out but, while it was a positive result, he admitted better performances are required.

"I think against Napoli we played very badly, we weren't aggressive enough, and I have to congratulate Monza as well for their performance tonight," he added.

"However, we defended well, were aggressive when they reached the edge of the area and know we can always score goals at the other end, but we definitely need to play better.

"As I said, we need to raise the bar. Atalanta will be a fundamental game for us to get back to the track we were on before Napoli."

Improvements are not just limited to the field, however, with significant changes in the club's hierarchy after president Andrea Agnelli, vice-president Pavel Nedved and other directors stepped down from their roles on Wednesday.

Chiesa feels the club is united in pursuit of their goals, as they bid for a successful second half of the season.

"Along with the new owners we will try to take Juve back to where the club deserves to be. We do our job on the field, the club does its off it."

Juventus claimed their spot in the Coppa Italia quarter-finals with a 2-1 win over Monza thanks to Federico Chiesa's sublime strike.

Chiesa, a second-half substitute in Thursday's clash at the Allianz Stadium, curled in off the post with 12 minutes remaining.

Moise Kean had given Juve an early lead but his effort was cancelled out by Mattia Valoti.

Kean saw what he thought would be a winner disallowed for offside, but Chiesa struck just after to settle the tie.

Nicolo Fagioli spurned a glorious chance for Juve in the opening moments but that miss mattered little as Kean headed Weston McKennie's cross into the far corner in the eighth minute.

Against the run of play, Valoti struck his third goal in as many Coppa Italia rounds to restore parity – Mattia Perin only able to push the forward's header into the roof of the net.

Juve's youngsters responded well, Samuel Iling-Junior firing wide and Matias Soule forcing a diving save from Cragno, but the hosts could not retake the lead before the break.

Kean came close to a second four minutes after the restart, bounding forward into the area, though Cragno was again on hand for Monza.

Juve had the ball in the back of the net after Danilo's shot deflected off Pablo Mari and against the crossbar, with Kean heading the rebound home, only for the offside flag to cut his celebrations short. 

The pressure finally told in the 78th minute, with Chiesa finding room down the left-hand side of the box and curling an effort in off the right-hand post.

Simone Inzaghi was left "very angry" after Inter had a third goal chalked off before conceding a late equaliser against Monza in their 2-2 draw on Saturday.

After Matteo Darmian's early opener was pegged back by Patrick Ciurria, Lautaro Martinez seized upon a Pablo Mari error to put Inter back ahead and seemingly on course for victory.

But with the score 2-1, referee Juan Luca Sacchi blew for a foul as a free-kick was swung into the Monza box, which Francesco Acerbi nodded in, for a contentious Roberto Gagliardini push.

With a goal that likely would have killed the game off ruled out, Inter suffered late heartbreak as Luca Caldirola scored in the 93rd minute to snatch a point for Raffaele Palladino's side and deny the Nerazzurri a fourth straight Serie A victory.

Inzaghi was fuming after the match, believing the referee's early whistle cost his side all three points as they missed the chance to move within five points of leaders Napoli, ahead of the Partenopei's visit to Sampdoria on Sunday.

"I'm very angry at what I saw," Inzaghi told reporters. "Unfortunately, after five years of VAR, there was an error that penalised us.

"A clear mistake on Acerbi's goal, there are two Monza players who fell between them. It's a huge disappointment on our part.

"I complimented Palladino, [but] without that mistake we would have won the match."

Romelu Lukaku impressed for Inter as they ended Napoli's unbeaten start to the season on Wednesday, but Inzaghi opted to start Martinez alongside Edin Dzeko up top against Monza, over the Belgium international.

With Lukaku struggling for fitness, Inzaghi is unsure when the striker will be back to his best, saying: "Time will tell, he's training in the best possible way.

"He had a very good first half with Napoli, today it was difficult. We'll do the analysis tomorrow when we'll be more rested."

Asked whether he felt Inter sat back too much late in the game, inviting Monza on, Inzaghi replied: "In the first half we conceded little or nothing.

"There are always difficult opponents, Monza are organised and have excellent players.

"Without what we've seen [Acerbi's disallowed goal], there wouldn't have been this question.

"Now we start again. It's normal that there is huge disappointment on everyone's part."

Inter missed the chance for a fourth straight Serie A victory as Luca Caldirola's late equaliser snatched a 2-2 draw for Monza on Saturday.

Simone Inzaghi's men ended leaders Napoli's unbeaten start to the season on Wednesday, and they got off to a great start at U-Power Stadium as Matteo Darmian fired in from Alessandro Bastoni's cross.

Ater Patrick Ciurria superbly levelled, Lautaro Martinez looked to have earned Inter victory when he took advantage of Pablo Mari's error to smash his side 2-1 ahead.

However, substitute Caldirola nodded home in the 93rd minute to spark jubilant celebrations from the hosts and deny Inter all three points.

Pablo Mari has returned to training with Monza less than two months after being hospitalised following a stabbing attack.

The on-loan Arsenal defender was one of five people injured in the incident, which took place at a supermarket near Milan in late October, while a cashier named Luis Fernando Ruggieri died.

Monza initially said Mari was expected to be out of action for two months, and the 29-year-old appears on course to recover within that timeframe after returning to training.

On Wednesday, Monza took to social media to post images of Mari with the ball at his feet, alongside the caption: "Look who's back".

Mari was welcomed onto the pitch at Monza's home Serie A fixture against Verona last month, a game the Silvio Berlusconi-owned side won 2-0.

Monza sit 14th in the Serie A table after 15 games and will resume their campaign with a trip to Fiorentina on January 4.

Monza and Bologna will observe a minute's silence before Monday's Serie A game to remember the man killed in a stabbing attack that left Pablo Mari injured.

Home side Monza will also wear special shirts bearing the message 'Come back soon, Pablo', ahead of their clash with the Rossoblu.

Mari, on loan to Monza from Arsenal, was one of five people injured in the incident near Milan on Thursday, in which a suspect was disarmed by onlookers and subsequently arrested.

A shop cashier named Luis Fernando Ruggieri died in the attack, and Monza have since sent condolences to his family.

Mari was visited in hospital by Monza chief executive Adriano Galliani and head coach Raffaele Palladino before undergoing back surgery on Friday.

The centre-back, who said he felt "lucky" to be alive after the attack in Assago, was discharged from hospital on Sunday and will reportedly be out of action for around three months.

Palladino revealed Monza originally considered requesting a postponement of Monday's match following the news, but then said the side were motivated to play, declaring: "Our duty is to play and go on the pitch and give everything for our team-mate."

Monza said in a statement on Sunday: "Before the kick-off of Monza-Bologna, a minute of silence will be observed at the U-Power Stadium to remember Luis Fernando Ruggieri, victim of Assago's insane attack.

"Furthermore, in the pre-match warm-up, the red and white players will wear a special T-shirt dedicated to Pablo Mari."

Pablo Mari has been discharged from hospital three days after the on-loan Monza defender was stabbed in a supermarket.

The Spanish centre-back, who joined Monza from Arsenal on a season-long loan deal in August, underwent back surgery after he was attacked near Milan on Thursday.

One person died and Mari was among five who were injured in a terrifying incident, with a suspect arrested after being disarmed.

Mari said he felt lucky to be alive, and the 29-year-old was on Sunday allowed to continue his recovery at home as he faces being out for at least two months.

A statement from Serie A club Monza said: "Pablo Mari was discharged from the hospital this morning, returned home and now begins a period of absolute rest.

"AC Monza sincerely thanks Professor Osvaldo Chiara and all the professionals of the Trauma Center of the Niguarda Hospital in Milan.

"Pablo, we are waiting for you!"

Monza head coach Raffaele Palladino has said Mari's team-mates will be playing for him when they face Bologna on Monday.

"It's not that we didn't want to play. The first news shook the whole group, and it's normal that we were shocked," head coach Palladino said when asked about not postponing the game.

"Initially we thought about a postponement, but the team reacted well, especially when they learned that Pablo was out of danger.

"A bad week, but at the same time beautiful. Pablo Mari is a miracle worker. Our duty is to play and go on the pitch and give everything also for our team-mate. We have no regrets over not postponing."

Raffaele Palladino says Monza will play for Pablo Mari when they face Bologna after the defender was injured in a multiple stabbings incident at a supermarket near Milan.

One person died and Monza's on-loan Arsenal centre-back Mari was among five who were injured during a terrifying incident, with a suspect arrested after being disarmed on Thursday.

The Spanish defender is expected to be out of action for at least two months after successful back surgery.

"It's not that we didn't want to play. The first news shook the whole group and it's normal that we were shocked," head coach Palladino said when asked about not postponing the upcoming game.

"Initially we thought about a postponement, but the team reacted well especially when they learned that Pablo was out of danger.

"A bad week, but at the same time beautiful. Pablo Mari is a miracle worker. Our duty is to play and go on the pitch and give everything also for our team-mate. We have no regrets over not postponing."

Former Juventus winger Filippo Ranocchia echoed Palladino's sentiment as he assured Monza will have Mari on their minds in their next Serie A clash.

"We couldn't believe it, it seemed absurd that one of our team-mates had been stabbed while shopping with his family. It was shocking news for everyone," Ranocchia told La Gazzetta dello Sport.

"When we heard that his life was not in danger it was a huge relief, we wanted to go and see him right away, but the team told us it was better to wait.

"After the operation. We knew he had to sleep, but we sent him messages in the team chat. When he woke up and wrote to us that the worst was over and that he couldn't wait to come back, it was beautiful.

"We will play for Pablo but also for Luis Fernando Ruggieri who lost his life in this crazy attack. Our thoughts go out to him, to his loved ones and to all the people involved in that night of terror."

Former Napoli defender Massimo Tarantino does not believe he is a hero, despite stepping in to halt the man responsible for multiple stabbings at a supermarket near Milan.

One person died and Monza's on-loan Arsenal defender Pablo Mari was among five who were injured during a terrifying incident on Thursday.

A suspect was arrested after he was disarmed by Tarantino, who has explained what prompted him to step in.

He told Stats Perform: "I was with my wife and daughter, we were at the till. We were putting the stuff on the checkout belt, and we realised [that something was going on], because there were very loud screams. We all kind of stopped at the tills, trying to figure out what was going on.

"But then there were more screams, one after the other in the space of a few seconds. At that point, the whole supermarket was kind of frozen, trying to figure out what was going on.

"After a few seconds, from one of the aisles right next to our till, someone came out who was probably one of those who had been stabbed; he was shouting for help and had blood all over his shirt. At that point there was a bit of panic, because people were clearly running away as they couldn't understand what had happened.

"After a few more seconds, another man came out. It was the person with the knife who was unfortunately aiming at the tills where I was with my wife and child. There wasn't much distance from that lane to the tills, about fifteen metres. So the instinctive reaction was to push my wife and daughter away and run.

"He was already almost there [close to me]. But in front of me there was this other employee who was between me and him, and he got stabbed. In the stabbing, they probably both lost their balance and fell into the checkout shelves where all the sweets are. Then I had the instinct not to run away.

"I had taken a step back, but I didn't run away and took advantage of the fact he was on the ground. I kicked him in the hand where he held the knife, and at that point he lost it, but it wasn't too far away, so I quickly ducked down and threw it far away and immobilised him. At that point he had no reaction.

"All of this happening in an atmosphere of terror, with blood on the ground. A bit of a strange atmosphere."

In spite of his actions, Tarantino – who played for Napoli between 1989 and 1996 and coincidentally also had a loan spell with Monza during his career – refused to be labelled a hero.

"No, I don't feel it belongs to me [this role] and I'm also a bit uncomfortable [with it]," he said. "I think heroes are other people. There are definitely people who do things that are impossible to do. They deserve, perhaps, that recognition.

"I, again, just found myself in the wrong place at the wrong time, and maybe instinctively decided to make the right choice, but nothing more than that."

The 51-year-old said his instinct was to "protect my family" and insisted it was not something he thought a great deal about at the time, adding: "I think these are irrational moments. I didn't think, I didn't reason. I just saw this person heading towards us.

"I think the first instinct is to protect my family, so I just had the instinct to move them away, to get them away, to run away. Immediately after he stabbed the employee, so a metre and a half away from me, my first reaction was to move one step back; but afterwards my instinct probably didn't make me run away, but told me that maybe that was the ideal moment to help.

"So I didn't go back, and I kicked this person in the hand holding the knife. But again, these things are irrational. When I think about it, it wasn't a calculated, intentional thing, it was just an instinctive reaction."

Tarantino confirmed he and his family are fine after the ordeal, though reiterated sympathy for those who were harmed.

"Yes, luckily for us it went well, unlike others; but we all came back home uninjured," he said. "On the one hand we're happy; on the other, I repeat, we're still sorry for everyone who unfortunately got caught up in this.

"The only message I have is that I want to wish the best of luck to all the people who suffered this physical assault and who have to deal with this problem right now.

"Then I think that all the other people, probably like me, like my wife and daughter, have had a bad night, a huge scare, and I hope that they, all of us, will get over it as quickly as possible.

"But the biggest wish goes out to all the people who suffered this physical attack; and I feel a huge sorrow for the family of the person who didn't make it."

Mari stated that he and his family are "fine" after the Spanish defender underwent back surgery following the attack.

Pablo Mari says he and his family are "fine" and the on-loan Monza defender expressed his gratitude for the support he has received after being stabbed on Thursday.

The Spaniard, who joined Monza from Arsenal on a season-long deal in August, is expected to be out of action for at least two months after undergoing back surgery following the horrific attack in a supermarket near Milan.

One person died and a suspect was arrested after being disarmed, with former Napoli footballer Massimo Tarantino named as being among those who stopped the assault.

Mari stated on Friday that he felt lucky to be alive before posting a picture of himself and his wife giving the thumbs up in hospital on Instagram.

The 29-year-old wrote: "After the hard moment we experienced yesterday, both my family and I want to communicate that fortunately we are all fine despite the circumstances.

"We want to thank all the messages of support and affection that we are receiving.

"In addition, we want to send our condolences and all our strength to the family and friends of the deceased person, and we sincerely wish that all injured people recover as soon as possible."

Pablo Mari underwent successful back surgery on Friday after Monza's on-loan Arsenal defender survived a stabbing attack near Milan.

The Spanish defender is expected to be out of action for at least two months, Monza said.

One person died in Thursday's attack and a suspect was arrested after being disarmed, with former Napoli footballer Massimo Tarantino named as being among those who stopped the assault.

Monza said in a statement: "The specialists of the general surgery-trauma team of the Niguarda hospital in Milan this morning carried out the surgery to reconstruct the two injured muscles on Pablo Marí's back.

"The surgery went well and a hospital stay of two or three days is expected."

Monza said a rehabilitation stage will begin once Mari is discharged.

"This type of muscle injury usually requires two months of rest before you can resume physical activities," the club statement added.

Italian newspaper Gazzetta dello Sport reported Mari recalling the attack, saying: "I was with the pushchair with my child inside and I felt an excruciating pain in my back. Then that man stabbed another in the throat.

"I was lucky, because I saw a person die in front of me."

A host of well-wishers have sent messages of support to Mari, including several of Monza's rival Serie A clubs.

The man who died in the attack was a shop cashier named as Luis Fernando Ruggieri.

Mari was visited in hospital on Thursday evening by Monza chief executive Adriano Galliani and head coach Raffaele Palladino.

Galliani said: "Pablo is an amazing guy. He had the strength to joke, telling me that he will be on the field on Monday.

"I brought him greetings from president [Silvio] Berlusconi and everyone, his team-mates who would have liked to come here even though, obviously, it was not possible."

Galliani said Mari "was probably saved by his height", as the stab injury missed his vital organs.

The former Milan executive added: "From a psychological point of view it seems to me that there are no problems, even if I am not a doctor."

Pablo Mari believes he is "lucky" to be alive after Monza's on-loan Arsenal defender survived a stabbing attack near Milan.

The Brazilian centre-back was one of several people injured in the attack, while one person died and a suspect was arrested after being disarmed. 

It was widely reported that former Napoli footballer Massimo Tarantino was among those who stopped the attacker.

Italian newspaper Gazzetta dello Sport reported Mari as saying: "I was with the pushchair with my child inside and I felt an excruciating pain in my back. Then that man stabbed another in the throat.

"Today I was lucky, because I saw a person die in front of me."

The man who died in the attack was a shop cashier named Luis Fernando Ruggieri, to whose family Monza sent their sympathies.

Arsenal said on Thursday they had been informed that Mari, who is spending the season in Serie A, was "not seriously hurt".

Mari was visited at the Niguarda hospital on Thursday by Monza CEO Adriano Galliani and head coach Raffaele Palladino.

Galliani said: "Pablo is an amazing guy. He had the strength to joke, telling me that he will be on the field on Monday.

"I brought him greetings from president [Silvio] Berlusconi and everyone, his team-mates who would have liked to come here even though, obviously, it was not possible."

Galliani added Mari "was probably saved by his height", as the stab injury missed his vital organs.

Reports in Italy said Mari would undergo surgery on Friday to deal with the wounding he suffered during the incident, which took place in the town of Assago.

Monza issued a statement that read: "Dear Pablo, we are all here close to you and your family, we love you, keep fighting as you know how to do, you are a warrior and you will get well soon!"

Galliani added: "From a psychological point of view it seems to me that there are no problems, even if I am not a doctor."

Mari's father, meanwhile, told Spanish broadcaster Cope: "They have been very bad hours. They started calling me at 8pm and my heart skipped.

"I was able to talk to my son and he told me that he was fine and that he loved us very much."

Mikel Arteta says Pablo Mari "seems to be okay" after he was stabbed in an incident near Milan, while Arsenal said they have been told the defender, who is on loan at Monza, is "not seriously hurt".

The Brazilian centre-back was one of several people injured in the disturbing scenes at a supermarket in Carrefour, Serie A club Monza confirmed on Thursday.

Arteta, whose side were defeated in Europa League action against PSV, issued a brief comment on the situation when speaking to the media after the game.

"I just found out," he said. "I know that [Arsenal technical director] Edu has been in touch with his relatives, and that he's in hospital, and he seems to be okay.

"But I don't know, I will have a briefing now about the situation, what happened, and obviously we will be in touch with him, and hopefully he's okay."

Arsenal issued a club statement, explaining they had been in touch with Mari's agent.

"We are all shocked to hear the dreadful news about the stabbing in Italy, which has put a number of people in hospital including our on-loan centre-back Pablo Mari," it read.

"We have been in contact with Pablo's agent who has told us he's in hospital and is not seriously hurt.

"Our thoughts are with Pablo and the other victims of this dreadful incident."

Pablo Mari, the Arsenal defender who is on loan at Monza, is in hospital after being stabbed at a shopping centre on the outskirts of Milan.

The 29-year-old was one of several people injured during an incident at a supermarket in Carrefour.

Monza confirmed Mari is receiving care at Niguarda hospital in Milan, but his condition remains unknown.

According to reports, the suspect was arrested by police and subsequently taken into custody.

Mari has made eight appearances for Monza in Serie A this season, scoring in their 2-0 victory over Spezia earlier this month.

Milan head coach Stefano Pioli conceded Charles De Ketelaere "has to do more", as the Belgian's slow start to life at San Siro continued.

The 21-year-old was a marquee addition in the pre-season transfer window, penning a five-year deal after the Serie A champions splashed a reported €36million to secure his services from Club Brugge.

Expectations were high after 14 goals and nine assists in Belgium's top flight last season, but he is yet to make such an impact in Milan, contributing just a single assist in his first 10 Serie A appearances.

Pioli has made it clear he is expecting more from the Belgian, who is likely to represent his nation at the World Cup.

"De Ketelaere has the quality to make an impact in our offensive play. He has to do more, he knows that too," Pioli told Gazzetta dello Sport.

"He still needs time, but the will of the boy counts. If you play in a top club, like Milan, you absolutely have to accept this competition and you have to do every day better than your teammate to convince the coach."

In further comments made to DAZN after Saturday's 4-1 win over Monza, Pioli expressed his understanding that it is still early days, adding: "Charles has only been here for a few months. I had intended to only play him for 15 minutes this evening, but we had to rush it because of that injury [to Braham Diaz].

"He has the quality, he just needs to believe in himself to really bring that potential out. He’s an intelligent lad, he knows how good he is, but it is a process and will require some time with good and not so good performances to get there."
