Milan ended their Serie A campaign with a disappointing 3-3 home draw against relegated Salernitana on Saturday in what was the last game at the club for coach Stefano Pioli and striker Olivier Giroud.

The Rossoneri looked set to cruise to victory when Davide Calabria put them 3-1 up in the 77th minute at San Siro.

Rafael Leao, who may well be on the move in the upcoming transfer window, had put Milan ahead after capitalising on a dreadful mistake from Salernitana goalkeeper Vincenzo Fiorillo in the 22nd minute.

Giroud doubled the advantage five minutes later, volleying home from an Alessandro Florenzi corner to mark his farewell appearance in style before he joins MLS club Los Angeles FC.

Salernitana pulled a goal back through forward Simy in the second half before Calabria restored the hosts' two-goal lead, with Pioli seemingly sailing towards a victory in his last match.

Yet Junior Sambia and Simy levelled with two quick-fire goals in the dying moments to deny second-place Milan a victory to end the season.

Data Debrief: Giroud heads off into the sunset in style

Giroud finished the Serie A season with 23 goal involvements (15 goals and eight assists); only twice in his career has he managed a better tally in a single season in the big five European leagues: 24 in 2013-14 with Arsenal and 30 in 2011-12 with Montpellier.

Indeed, the 37-year-old is the oldest player among those with at least 23 goals involvement in the big five European leagues this season.

Christian Pulisic grabbed an assist, meanwhile, to become only the second Milan midfielder to be involved in 20+ goals (12 goals, eight assists) in a single Serie A season, after Kaka (20 in 2005-06, 26 in 2007-08, 25 in 2008-09) in the last 20 seasons.

An electric first-half display from Rafael Leao steered AC Milan into the Europa League quarter-finals as 10-man Slavia Prague succumbed 3-1 on the night and 7-3 on aggregate.

Just as they had in the first leg, the Czechs paid the price for a red card, Tomas Holes dismissed after just 17 minutes for a dangerous tackle on Davide Calabria.

The Rossoneri cashed in three times before the break, Leao lending a helping hand as Christian Pulisic and Ruben Loftus-Cheek netted before bending in a spectacular strike of his own from distance.

Slavia had not lost at the Fortuna Arena all season but were unable to summon a serious battle for their Serie A opponents until Matej Jurasek grabbed a late consolation.

They did manage one attempt before the tie slipped irretrievably out of their grasp, Mojmir Chytil denied by the outstretched boot of Mike Maignan – the goalkeeper’s last real contribution before coming off injured.

Within a couple of minutes, Holes went studs first into a challenge with Calabria and saw red after a VAR check, leaving his side to face the majority of the match at a numerical disadvantage.

Jindrich Stanek kept the hosts in it with a pair of sharp saves but could not hold back the tide when Leao played in Pulisic, who rifled home after turning inside with a smart touch.

With the resistance broken, Milan wasted no time getting another, Loftus-Cheek providing the final touch after Theo Hernandez’s silky one-two with Leao put it on a plate for the Englishman.

With the pressure off, Fikayo Tomori will regret picking up a booking that will rule him out of the first leg of the quarter-finals but the celebrations resumed in added time before the break, the electric Leao letting fly with a beautiful curling effort from 30 yards.

The second half unfolded at a gentler pace, the home side focused on containment and the Italians emptying their bench in acknowledgement that they had wrapped things up.

Chances did occasionally appear, Lofus-Cheek slotting wide and Olivier Giroud aggrieved when he was unable to add his name to the scoresheet just after the hour mark.

To their credit, the Czech side did not lie down, firing a warning shot via Michal Tomic’s breakaway and then getting one back through Jurasek. He had only just come on when he picked up Christos Zafeiris’ pass and picked out the bottom corner of the net from the edge of the area.

AC Milan head coach Stefano Pioli will do his best to make amends for their disheartening Champions League exit by guiding the Rossoneri back into the competition through Serie A once again.

Milan are keen to get over the disappointment of their failure to progress to the knockout stages – Wednesday’s victory at Newcastle was only enough to secure third in their group and Europa League football – with a home win against Monza that will help them maintain their pursuit of second-placed Juventus, currently eight points clear.

Back-to-back league successes against Fiorentina and Frosinone were followed by a frustrating last-minute defeat at Atalanta last weekend and Pioli wants a response to both setbacks in Sunday’s lunchtime kick-off.

Pioli said at a press conference: “My big regret is that the team are not making the most of their potential right now, in Europe and in the league, so that’s what I must work on trying to change.

“This squad has so much potential, we created so many chances especially in the Champions League and lacked that bit of determination and quality. With that, we would have been here celebrating Champions League progress.

“Clearly, we can only now try to consolidate third place in Serie A and then try to do more. Our minimum objective is to qualify for the Champions League again, that is the very least we can aim for.”

Davide Calabria is suspended for the Monza clash after his dismissal in Bergamo so Theo Hernandez will be captain as Pioli tries to reckon with a defensive crisis.

Pierre Kalulu, Mattia Caldara, Marco Pellegrino and Malick Thiaw are all out injured, along with goalkeeper Marco Sportiello, and only one of academy product Jan-Carlo Simic and Simon Kjaer is likely to be fit enough to slot into the backline.

For Monza, Argentinian midfielder Alejandro Gomez is only two months into a two-year doping ban, with on-loan Torino defender Armando Izzo and Hellas Verona loan forward Gianluca Caprari among the key injury absentees.

Sunday’s visitors snapped a poor run of three games without a win by beating Genoa 1-0 last time out but away wins have been hard to come by so far for the mid-table side from the Stadio Brianteo.

Monza boss Raffaele Palladino said at his Saturday press conference: “We are satisfied so far but must keep our feet on the ground and improve on many aspects, such as being more effective in front of goal.

“Playing at San Siro is a source of pride. I believe Monza can do well and put Milan in difficulty. We are set up for this, to compete with anyone, anywhere. We must not be afraid of anybody.”

Milan moved to the Serie A summit as Ismael Bennacer and Zlatan Ibrahimovic struck late to hand them a pulsating 4-2 win over nine-man Bologna.

Rafael Leao and Davide Calabria scored either side of Adama Soumaoro's dismissal to give the Rossoneri a healthy advantage at the interval.

That was wiped out in the space of seven minutes at the start of the second period, however, with an Ibrahimovic own goal and a Musa Barrow strike restoring parity at the Stadio Renato Dall'Ara.

Bologna had a second man sent off before the hour mark, Roberto Soriano given a straight red card for a late challenge, and Stefano Pioli's Milan landed a memorable three points thanks to fine late strikes from Bennacer and Ibrahimovic.

Leao put Milan ahead in the 16th minute with a deflected strike, before Soumaoro was shown a red card for bringing down a clean-through Rade Krunic just outside the area four minutes later.

Milan took advantage of their numerical superiority in the 35th minute, Calabria lashing home a second from 15 yards.

The hosts stormed back at the start of the second period, though, with Ibrahimovic – making his first start since May 9 – heading into his own net four minutes after the interval to give Sinisa Mihajlovic's side hope.

Barrow then remarkably drew Bologna level in the 52nd minute, slotting past Ciprian Tatarusanu after being played in by Soriano.

Rossoblu captain Soriano was then given his marching orders after a VAR review six minutes later for an ugly challenge on Fode Ballo-Toure.

The hosts held firm until the 84th minute when Bennacer powered into the bottom-left corner from 20 yards, while Ibrahimovic added gloss to the scoreline with a whipped finish from the same distance six minutes later.

Milan have handed defender Davide Calabria a new four-year contract.

Calabria has spent over six years in Milan's first team, making 151 appearances, and has now extended his stay until 2025.

The 24-year-old only had one year left on his previous contract, meaning the new deal is a three-year extension.

Academy product Calabria played 32 Serie A games last season, 30 of which were starts, with both of those figures being career highs.

"AC Milan is delighted to announce the contract extension of Davide Calabria until June 30th 2025," the club said in a statement on Friday.

Stefano Pioli's men finished second in Serie A last season and have already had a busy transfer market.

They completed the signing of Sandro Tonali on a five-year deal from Brescia on Thursday, the midfielder having spent last season on loan with the Rossoneri.

Pioli has urged the club to strengthen his squad if they are to be a force next season and insisted Franck Kessie is happy at San Siro amid speculation over his future.

He is hoping not to lose any more stars after Gianluigi Donnarumma departed at the end of his contract and Hakan Calhanoglu joined city rivals Inter in a surprise move.

In the other direction, Fikayo Tomori returned to San Siro in a permanent deal from Chelsea and Lille goalkeeper Mike Maignan replaced Italy international Donnarumma.

Davide Calabria should be fit to return for next season after undergoing surgery on a sports hernia, Milan have confirmed.

The full-back has not been included in Italy's provisional squad for Euro 2020, so his season was already over after helping Milan qualify for the Champions League with a 2-0 win over Atalanta on Sunday.

Calabria played 36 times across all competitions for Milan in 2020-21, scoring twice and providing one assist from 26 chances created, while also helping Stefano Pioli's team keep 11 clean sheets.

The 24-year-old may well feel hard done by to have missed out on Roberto Mancini's 33-man selection, which will be cut to 26 by the deadline of midnight on June 1.

His numbers stack up well when compared to the three right-backs included in Mancini's squad – Alessandro Florenzi, Giovanni Di Lorenzo and Manuel Lazzari.

Napoli's Di Lorenzo is the be standout option from an attacking perspective, having scored four goals and teed up a further seven in all competitions, with his 62 chances created far better than the efforts Calabria, Florenzi or Lazzari (both 28).

Defensively, however, Calabria seems to the outstanding candidate. He attempted 105 tackles, 10 more than Di Lorenzo and far ahead of Florenzi (38), who spent the season on loan at Paris Saint-Germain, and Lazio wing-back Lazzari (29), with an impressive 61.9 per cent success rate. 

Calabria went into 333 duels, winning 200 – more than either Florenzi or Lazzari – and he won 32 of his 62 aerial battles, with Di Lorenzo bettering the Milan man for interceptions (47, compared to 41).

He did attempt fewer open-play crosses (78) than any of his counterparts, with only 21 of them finding a team-mate, although Calabria's tally of 130 passes into the final third was second only to Di Lorenzo (153).

Nevertheless, Calabria's focus will now be on Milan's 2021-22 campaign, with the club confirming a planned recovery time of six weeks.

A Milan statement read: "The operation, performed by videolaparoscopy by Dr Giuseppe Sansonetti in the presence of Rossoneri doctor Lucio Genesio, was perfectly successful."
