The Serie A giants confirmed the news in a statement on Saturday.
"Mario Corso has passed away, a man who was Inter through and through and an eternal champion, gifted with infinite class," it read.
"He enchanted the world with his left foot in a team that marked an era.
"The thoughts and love of every one of us go to his family at this difficult time."
Corso was one of the standout performers in Helenio Herrera's celebrated Inter side that won back-to-back European Cups in 1963-64 and 1964-65.
He was long established before that period, making his debut as a 16-year-old. Corso's goal against Bologna in November 1958 made him the youngest goalscorer in Inter history at 17 years, three months and five days.
A winger gifted with an exquisite left foot, Corso won four Serie A titles and made 23 appearances for Italy.
Overall, his Inter career spanned 1957 to 1973, during which time he amassed 502 appearances and 94 goals.
Inter remained 13 points behind runaway leaders Napoli after going down 1-0 at home following a first-half Milan Skriniar red card.
Empoli were good value for their win against Inzaghi's out-of-sorts side, and the head coach appeared to recognise that as he sought to move on swiftly from this match.
"We have to archive it immediately," he said. "We will have another difficult game, and we have to forget immediately, looking ahead.
"Of course, we will analyse the mistakes, but we have to think about the next matches."
The season is now at the halfway stage, and Inzaghi acknowledged Inter must improve.
"This is a defeat that stings," he told DAZN. "We finish the first half of the season with 37 points and many regrets.
"Now, we know we'll have to do better over the second part."
However, midfielder Hakan Calhanoglu is remaining optimistic, saying in an interview with Sky Sport: "Thirteen points [to Napoli] is a huge gap, but we have to keep going and not stop.
"I know it feels hard to believe, but there's still a long way to go."
At a news conference, Italian prime minister Giuseppe Conte confirmed Sunday's fixtures in the Lombardy and Veneto regions, including the Hellas Verona-Cagliari and Atalanta-Sassuolo clashes, would not go ahead.
The move comes as part of preventative measures against the spread of the coronavirus, officially named Covid-19, after two people died and dozens more reportedly tested positive.
Saturday's scheduled Serie B match between Ascoli and Cremonese was earlier postponed and up to 88 amateur football matches were also called off, according to Italian news agency ANSA.
In a short statement, Inter announced only that their meeting with Sampdoria at San Siro was postponed "to a later date".
The third-placed Nerazzurri sit six points behind Serie A leaders Juventus, who won 2-1 against SPAL on Saturday.
Sunday's three other games are expected to go ahead as planned.
Genoa are due to host title-chasing Lazio, with Torino to face Parma and Roma entertaining Lecce.
The 27-year-old Italy international, who has made 175 league appearances for Inter, has a strain in the rectus femoris of his right thigh, the club said in a statement.
"His condition will be reassessed next week," the club added when announcing his injury on Tuesday.
Inter, sixth in the Serie A standings with eight points from five matches, visit Udinese on Saturday, before hosting Red Star Belgrade in the Champions League next Tuesday.
Simone Inzaghi's side will be desperate to recover Barella for their clash with surprise league leaders Torino on October 5.
Barella impressed as the Nerazzurri began their Champions League campaign with a goalless draw at Manchester City last week, creating two chances for team-mates and ranking first among all Inter players for possession regains (seven) and passes played in the final third (10).
The Netherlands striker is expected to leave Barca this month, with Inter among the clubs reported to be keen to sign him.
Following Barcelona's signing of Robert Lewandowski, Depay has found first-team opportunities difficult to come by – making just two starts in LaLiga this season.
Depay's lawyer Sebastian Ledure has denied that the 28-year-old, also linked with the likes of Atletico Madrid, could be on his way to San Siro.
"There are no negotiations ongoing for Memphis to join Inter," he told Fabrizio Romano.
"I can deny all these links, it's not a possibility that we are discussing."
The former Lyon and Manchester United forward joined Barca in 2021 and was an unused substitute in the 3-1 Supercopa de Espana victory over Real Madrid on Sunday.
Inter had the opportunity to return to the top of Serie A, at least until Juventus played later on Sunday, but toiled to a second successive league draw.
Substitute Alessandro Bastoni scored his first Nerazzurri goal to seemingly set the away side on course for a scrappy win 19 minutes from time, only for Marco Mancosu to hit back.
Conte was disappointed with the lack of vigour in his side's display, claiming they are merely "a normal team" when playing at that level.
"The draw stems from the fact that we must always go at 200 [km] an hour," he said.
"When someone is below that, we cannot afford it. Then the level of the team drops and it can happen that you draw a game that you should have taken three points from.
"We are not a team that manages to bring home the victory going at an average speed. We must always go to the maximum - we have done so in all the matches of the first half of the season.
"When we can't get to the maximum, we are a normal team."
Conte was called out by Jose Mourinho earlier in the week amid the perception he had openly discussed Inter's interest in Tottenham midfielder Christian Eriksen.
Inter chief Giuseppe Marotta spoke about Eriksen on Sunday, but Conte was not willing to follow suit.
"This month is difficult to manage. I think I have been very clear - even if sometimes the things I say are then exploited," he said. "I don't want to talk about the market.
"That is for the club - I am the coach and I have to try to bring out the best in my players."
Inter came from behind with two goals in the final five minutes of a wild game in their season opener against Fiorentina at San Siro on Saturday.
Franck Ribery was outstanding for Fiorentina and teed up two goals in the second half, with substitute Dusan Vlahovic squandering a chance to give the visitors a 4-2 lead after another exceptional piece of play from the veteran Frenchman.
Ribery was hauled off after 83 minutes, with Fiorentina taking the chance to give him a rest, but the Viola were then rocked by late goals from Romelu Lukaku and Danilo D'Ambrosio that earned 2019-20 Europa League runners-up Inter all three points.
Inter head coach Conte sent on Achraf Hakimi and Alexis Sanchez, and it was their crosses that led to the late goals. Like Hakimi, former Barcelona player Arturo Vidal was introduced off the bench for a Nerazzurri debut in the second half.
Conte said via Inter's website: "The changes brought benefits. I am happy and the guys know it. It will be a long and tiring season. There will be room for everyone and everyone will be needed.
"The three points are important, we have had many chances and we found the way to goal four times.
"This is the positive aspect but at the same time we cannot concede three goals like this."
The former Juventus and Italy boss said Inter lacked the right balance between defence and attack.
"In this respect we were not careful and we need to improve," Conte said. "If you want to play high-level championships, balance is the basis of everything."
Conte also saw signs from Christian Eriksen that the former Tottenham midfielder could have a big role to play this season, having struggled to adapt to Serie A last term.
"Compared to when he arrived he has increased the engine revs, he is playing in his ideal position," Conte said.
"I think he had a good game. We are working with him because we know he has important qualities.
"I have faith in him, he is a guy who trains very well and makes himself available to the team. I hope he will soon be able to strike the spark that will take him to the maximum."
Inter had forged ahead in the first half courtesy of Romelu Lukaku before Bologna's Roberto Soriano received a red card for dissent after 57 minutes.
Lautaro Martinez could have all but wrapped up the win from the penalty spot five minutes later but Lukasz Skorupski kept out his tame effort.
That gave the impetus to the visitors, who roared back to steal a stunning winning thanks to goals in the final 16 minutes from Musa Juwara and Musa Barrow, either side of a red card for Inter's Alessandro Bastoni.
Conte, who spent close to an hour in the changing room with his side before talking to the media, could not hide his frustration and says his players should be angry at their display.
"The disappointment is enormous, at least as far as I'm concerned," he told reporters. "I hope this disappointment that I feel is also felt by the players for at least one per cent.
"I am angry at myself because I'm the manager. I have my responsibilities; I am the one who directs the situation and it is right that I am very angry first of all with myself. Then I think that the players must also be with themselves."
The setback leaves Conte's side four points behind second-placed Lazio and just one ahead of Atalanta in the battle for Champions League qualification.
Conte is under no illusions that he is expected to win trophies at Inter and says he fully expects to be scrutinised when things do not go well.
"Situations are evaluated only by facing them," he added.
"For me this is the first year of working with Inter and I have taken a situation with many situations to improve. At the same time, I also say that it is right to challenge everyone, me first.
"I was brought here for a winning project and to bring Inter back to winning things. Clearly, the victory does not come overnight, but many situations leave a lot of bitterness. You think you are at a level and instead you are at a much lower level.
"From here to the end we will all have to prove that we deserve Inter. Otherwise it is right to make other decisions too."
Second-placed Inter visit Leverkusen in sixth place with three games remaining in the league stage of the competition.
"We're playing against a team who boast absolute quality, one that has won the last five games and only lost three matches in the past year and a half," Inzaghi told reporters on Monday.
"They're on a great run, and we've prepared in the best possible way. We know the importance of the match."
Asked about Inter's strong position in the Champions League, Inzaghi said they were not taking anything for granted.
"We all know the path we're on. We want to keep going, knowing we're facing a strong opponent for sure. We'll need to be at our best," he said.
"Leverkusen have great quality, so it's important to continue that momentum and show our determination.
"They come at you very quickly when they lose the ball. You have to do well in both phases against them."
Inter have defensive concerns, as Denzel Dumfries has not travelled due to a high fever, further depleting the back line.
"Dumfries had a fever of 38 Celsius (100.4 Fahrenheit) today, so he couldn't train or come here," Inzaghi said.
"In defence, the absences of him, Benjamin Pavard and Francesco Acerbi complicate things."
There are also worries over Tajon Buchanan's reported muscle fatigue and an injury scare for centre-back Alessandro Bastoni in Friday's Serie A win over Parma, but Inzaghi remains upbeat.
"We have some players absent as everyone does at the moment. But I have total confidence in everyone."
The derby d'Italia, scheduled to take place behind closed doors on Sunday, was one of five top-flight fixtures to be postponed in Italy due to the spread of the coronavirus.
Instead, the games will be played on May 13, meaning the Coppa Italia final – which the Nerazzurri could yet be involved in – has been pushed back to May 20.
Inter director Beppe Marotta criticised the timing of the decision taken by officials, saying the championship had been "distorted" while raising concerns over whether upcoming domestic fixtures will go ahead.
"Is the league at risk of not ending? Yes, if more matches were to be postponed, then yes. And then I ask myself - why was the Juve-Inter date decided before the Inter-Sampdoria date? On what basis?" Marotta said to La Gazzetta dello Sport.
"The league is distorted. It is altered in its balance. Just think of the injuries and disqualifications. And then there is the psychological aspect. Again, Inter are damaged, our schedule in May is incredible."
Speaking to the same outlet, Dal Pino revealed how the Lega Serie A had offered to push back the derby by 24 hours, allowing supporters to watch proceedings at the Allianz Stadium, but that plan was rejected by Inter.
"On Friday, CEO [Luigi] De Siervo and I proposed to Inter the idea of moving the game with Juventus to Monday evening so that it could be played with a crowd present," Dal Pino told La Gazzetta dello Sport.
"Inter categorically refused to take the field, so they should take responsibility for their decisions and not talk of unsporting situations or a distorted league.
"Marotta represents the needs of Inter, I have to look after the general interests of an entire Serie A division, which unfortunately means daily conflicts of interests tied to each and every club.
"My job is to promote Italian football and its image to the world, so transmitting games in empty stadiums would’ve been a terrible calling card for the country.
"The decision was down to me, but the clubs involved were contacted by telephone, so we know that they all had positions which were difficult to reconcile."
Inter are due to play Napoli on Thursday in the second leg of their Coppa Italia semi-final, having lost the first meeting 1-0 at San Siro.
Zielinski had been widely expected to join the Nerazzurri after running down his contract with Napoli, who he helped to the Scudetto in 2022-23.
The Poland international joined the Partenopei for €16million in 2016 following spells with Udinese and Empoli, making 364 appearances for the club throughout a distinguished eight-year spell.
The 30-year-old has now penned a four-year contract with Simone Inzaghi's Serie A champions and is hoping to help them compete for more silverware next term.
He told the club's website: "I will try to give it my all to make the fans happy, they are fantastic and San Siro is one of the best grounds in Italy.
"I will do my best to show my skills and bring other trophies to the club. I am very happy because I'm joining one of the best sides in the world. It is an honour, I can't wait to get started."
Zielinski will not be the only new face at San Siro, with former Porto striker Mehdi Taremi set to arrive as a free agent and Genoa goalkeeper Josep Martinez reportedly close to joining in a €13m deal.
Sensi moved to Serie A rivals Inter on loan with the option of a permanent deal at the start of the 2019-20 season.
Despite injuries marring Sensi's debut season at San Siro and the January arrival of Christian Eriksen, Inter are set to take up their option on the Italian midfielder.
"Sensi will be bought outright by Inter," Carnevali told Ceramicanda.
"There is no doubt, the Nerazzurri's decision is already made."
The season has been postponed since March due to the coronavirus pandemic, which has wreaked havoc globally.
Defending champions Juventus were a point clear of Lazio through 26 games at the time of postponement as officials try to restart the campaign.
Sassuolo were 11th and seven points above the relegation zone in Serie A.
"Prices for players will drop maybe, but ours won't. We're an expensive shop," Carnevali said. "The interruption of Serie A has cost more than €200million. For Sassuolo, it's between €10m and €12m.
"The damage of the season not resuming would rise to €800m and several companies would end up in court: Serie A also drives on B, youth teams, women's football...
"Sports minister Vincenzo Spadafora seems to be experiencing a moment of confusion, but I see new awareness emerging from the government and maximum willingness from clubs to comply with the required safety conditions."
The midfielder, who is on loan at La Viola from Roma, fell to the ground in the 17th minute, with medical personnel rushing to his aid, while his team-mates formed a protective ring around him.
Bove was taken away in an ambulance, while the referee escorted the players from the pitch to return to the dressing rooms.
A Serie A spokesperson confirmed the match would be postponed until a later date, while Sky Sport Italia reported the 22-year-old had regained consciousness and was breathing without aid.
Inzaghi's side finished 19 points clear of their closest rivals Milan in 2023-24, but they are currently two points behind leaders Napoli after eight matches.
They sit one clear of Derby d'Italia rivals Juve – who are the only unbeaten team remaining in the Italian top flight – ahead of Sunday's head-to-head clash at San Siro.
Speaking to reporters on Saturday, Inzaghi refuted the suggestion his team are clear title favourites, saying: "I don't like to talk much about favourites and things like that.
"This year it will be a more balanced championship than usual; many teams have spent a lot to close the gap that had been created.
"Juventus are the best team in Europe in terms of goals conceded, they have an excellent coach who I really like and they have invested a lot. They will remain protagonists throughout the year."
While Juve coach Thiago Motta and Napoli's Antonio Conte have both played down their own chances of title success, Inzaghi's past success does not allow him that luxury.
"I don't know if it's a strategy or something else, I can only speak for myself," Inzaghi said.
"We know that we start from the beginning of the season with clear goals, to play as many games as possible to ensure that we get as far as possible in the cups and try to be competitive in the league."
Inter enter Sunday's match with selection issues. Defender Francesco Acerbi is still out with a thigh injury sustained in the last league game, a 1-0 win at Roma, and midfielder Hakan Calhanoglu also went off injured in that match.
Kristjan Asllani could be in line to replace Calhanoglu, if he can recover from his own injury which has kept him out of Inter's last two games.
"We know what Calhanoglu represents for us, he is a world-class player. His natural replacement is Asllani, if he gives me the right guarantees he will play," Inzaghi said.
"He is a player who has improved a lot over the years, his misfortune is having Hakan ahead of him.
"Unfortunately he had a problem before Roma. Yesterday he had his first training session which didn't go badly and we will need to evaluate.
"In the same role we also have [Nicolo] Barella and [Piotr] Zielinski; I will carry this doubt until tomorrow evening."
Early goals from Giacomo Raspadori and Gianluca Scamacca made it a third straight league game without a win for the Nerazzurri, who also lost the first leg of their Champions League last-16 tie to Liverpool in midweek.
Inter consequently failed to reach the summit of the table despite leaders Milan being held by Salernitana on Saturday, though only three points separate the top three in the table. Inter sit two points adrift of Milan, with Napoli in third.
Sassuolo have now clocked up away wins against both Milan sides and Juventus this term, with head coach Inzaghi left frustrated by his team's poor application.
"I am very angry with the approach, because we had three days since Wednesday's game. We talked about the fact Sassuolo beat Juve and Milan away, they play great football and we had to be wary," Inzaghi said.
"We tried to do everything in the second half, created so many chances and were unlucky, but the fact remains we should have had a different approach.
"Sassuolo had great technical quality, they were fresher physically and it showed.
"We will analyse the situation, we know there are 13 games to go, we are all up there and want to keep going forward.
"The fact is a team that wants to win the Scudetto cannot get the approach as wrong as we did today."
Lautaro Martinez drew a blank for a seventh straight game, while Opta data shows that since the resumption of the league after the mid-season break Inter have recorded 100 shots (36 on target) but managed only six goals.
They remain the top scorers in Serie A, though, and Inzaghi is sure his side will soon start finding the net with more regularity.
"I don't think there is anxiety, the great champions are accustomed to these games. I think there was a lack of sharpness, there was some fatigue, both physical and mental," Inzaghi added.
"My staff and I tried to focus the players this week, but we conceded two early goals that we usually don't allow.
"We remain the most prolific side in Serie A this season and will get back to scoring goals soon. When you are a striker and don't score, you just have to stay calm, the goal will come."
Matteo Darmian and Roberto Gagliardini were hauled off at half-time for Denzel Dumfries and Edin Dzeko, and Inzaghi would have liked to have made more alterations.
"I would have happily changed more than two at half-time," he said. "We lost some of our organisation, we tried to open it up again, but we have to analyse what went wrong today.
"There's another match in [five] days [against Genoa], we know that we play continually and need to be stronger than absences, bans, injuries, setbacks, everything.
"We're all in there and will see what happens at the end of the season."
Hakan Calhanoglu scored with a stunning strike to cancel out Scott McTominay's opener for Napoli, but missed a penalty for the first time in eight years.
He had previously never missed a penalty in Serie A, netting 17 in a row before Sunday.
"I congratulated the team, if there was one side that should've won, then it was Inter. The second half was dominated by us," Inzaghi told DAZN.
"We went behind on a set play situation where we should've done better, but we kept our heads and did not allow Napoli practically anything.
"We hit the woodwork twice, missed a penalty, so I don’t know what more we could've done."
While Inter dominated the second half, the strike duo of Lautaro Martinez and Marcus Thuram were largely kept quiet.
Martinez managed just two shots, worth 0.24 expected goals (xG), hitting the target with neither, while Thuram did not manage a single attempt, though Inzaghi was still impressed by their displays.
"They worked hard for the team and kept us solid," Inzaghi said.
"As a coach, I have to leave the result aside and focus on the performance, which was excellent against a quality opponent."
With nearly a third of the Serie A season completed, the title race is shaping up to be tight with Napoli leading the way on 26 points. Atalanta, Fiorentina, Inter and Lazio, meanwhile, are all on 25.
"I said this would be a very balanced campaign and that is proving to be true, but I saw a wonderful Inter tonight," Inzaghi said.
"We could probably have made more of our chances, but let us not forget the strength of the side we were facing."
The Nerazzurri suffered their first loss of the Champions League season as they went down 1-0 at BayArena after Nordi Mukiele's late winner.
It marked the first goal Inzaghi's side had conceded in their opening six games, while they failed to register a single shot on target at the other end of the field.
And the Inter head coach acknowledged he wanted to see more from his players.
"It wasn't one of our best matches, but we faced a top-quality team that started better, hitting the crossbar early on," he said. "After that, we controlled the game - perhaps too much, as we should have been more daring.
"We lacked quality in the final 25 metres, and once we had the match under control, losing like this is frustrating because it ends our unbeaten streak.
"There's regret about conceding that goal. We needed to be more attentive. We played worse in the second half than the first, but there were no warning signs.
"When we started building possession, it felt like they were struggling to cope with our play. We should've added more quality, but today, we didn't show the level we’re capable of. We certainly needed to do more."
Nevertheless, Inzaghi also focused on the positives with Inter occupying fourth place in the league table - with the top eight seeded straight through to the knockout stage.
"Still, it doesn't take away from our journey," he added. "[On Wednesday], we'll probably be among the top eight, and in January, our destiny will be in our hands with two challenging matches.
"There's regret, but that's Champions League football. We move forward with our heads held high."
The Scudetto holders face the Swiss champions having already beaten Red Star Belgrade and drawn away to Manchester City.
But with so little time to get used to the different pitch material, Inzaghi preached cautiousness in his pre-match press conference.
"I will have to make careful evaluations, the synthetic changes things, it is not the same and that's why we will train here today, changing our habits," he said.
"We will have to get used to it in a short time, in the hour we will have on the pitch we will have to pay close attention."
Inzaghi would not be drawn on the poor form of their hosts, who are currently 10th in the Swiss Super League with just two victories from their opening 10 matches and two defeats in the Champions League.
Joel Magnin took temporary charge of Young Boys following Patrick Rahmen's dismissal earlier in the month, though the interim boss was in the same position last season when the club won the league title.
"They won the league last year and have had some initial problems. It is a physical team, which has played in the cups for many years," said Inzaghi.
"They are a structured team with a new coach who knows the environment. On Saturday against Luzern they played a good game, we will have to pay attention."
The Inter head coach has issues of his own, with midfielder Kristjan Asllani having missed Sunday's victory over Roma.
Hakan Calhanoglu also went off injured in that match, but Piotr Zielinski is expected to be available again.
"Zielinski did a good part of training yesterday and the feelings are positive, I will have to evaluate," said Inzaghi.
"I was happy with what [Nicolo] Barella did in front of the defence on Sunday, tomorrow one of him and Zielinski will play there.
"Barella, [Henrikh] Mkhitaryan and [Davide] Frattesi have spent a lot [of energy]. Frattesi will certainly play, then of the other three, two will start from the start and one will probably come on."
Inter produced an impressive performance at the Etihad Stadium, holding the team that beat them in the 2023 Champions League final to seal a memorable treble.
Matteo Darmian and Henrikh Mkhitaryan had huge chances to put the Nerazzurri ahead in the second half, though they were also fortunate to see Ilkay Gundogan miss two golden opportunities for City.
After becoming just the second coach to oversee a clean sheet in an away Champions League game versus Guardiola's City, Inzaghi heaped praise on his players.
"The players did really well, we knew the quality of our opponents, but we worked well and could have hurt them more in some situations," he told Amazon Prime Video Italia.
"In the final third we need to show skill and technique, which we do have in the squad.
"Against these sides like Manchester City and Real Madrid, you always seem like you might be able to score a goal, but then they manage to rescue it."
Midfielder Hakan Calhanoglu, meanwhile, said Inter were determined not to be intimidated by City following their defeat in the 2022-23 showpiece game.
"We wanted to show that we are not scared to play here. We play football the way they do, with sacrifice we showed that we can also play football," Calhanoglu said.
"We enjoyed ourselves against a very strong team and could also have won, but with the right courage and spirit of sacrifice, we proved that we can compete against anyone."
Inter will now turn their focus to the Derby della Madonnina against Milan in Serie A on Sunday.
"It will be a derby, we all know what that means for the club and our fans," Inzaghi said. "They never stopped singing tonight in Manchester.
"We will stay here overnight, fly back tomorrow and try to prepare the match in just a few days."
Marcus Thuram's hat-trick propelled Inter to a 3-2 victory over 10-man Torino on Saturday.
It was Inter's second 3-2 win on the spin in Serie A, moving them up to second.
Inter only conceded seven shots, but five of those were on target, with Torino's 1.61 expected goals (xG) showing the visitors created decent openings at San Siro, where Nikola Vlasic converted a late penalty to set up a grandstand finale.
"Clearly, we need to improve in some aspects, we pay a heavy price for every tiny distraction," said Inzaghi, who has seen Inter concede two goals in successive league matches for the first time since May 2023.
"We worked really hard on details that need to be whittled down, the lads have great spirit, but considering everything we did today, today's game shouldn't have ended 3-2.
"Seeing a team perform like this in three matches makes me want to congratulate these guys. We need to keep working the way we are, and in our penalty area, we all need to be more attentive.
"We're working on it, and we need to do more. Over the past two days, the team has trained extremely well, and we're trying to pay even more attention to the finer details."
Hat-trick hero Thuram, meanwhile, says the entire team must step up when it comes to defending.
"It's also the fault of the attackers, not just the defenders or the goalkeeper," he said.
"We are eleven players on the pitch and not conceding goals is part of everyone's job. We will try to improve in the upcoming games.
"There’s a lot of work, especially in the penalty area. For me, scoring is always a great feeling, but I always want to remain a player who helps the team above all."
Thuram's haul was the third time he has scored at least twice in a match this season, matching Erling Haaland.
Indeed, in 2024, only Juventus' Dusan Vlahovic has scored more Serie A goals than Thuram (13).
