Arkadiusz Milik scored with his first touch as a substitute to send Juventus through to the Coppa Italia final.

Juve had seen their 2-0 lead over Lazio from the first leg wiped out by a double from Valentin Castellanos.

But Poland striker Milik found the net seconds after climbing off the bench as Juve were beaten 2-1 on the night but progressed 3-2 on aggregate.

Juve will face either Fiorentina or Atalanta in the final next month.

The visitors were first on the attack and Filip Kostic’s blocked shot ricocheted to the feet of Andrea Cambiaso, whose low drive flew inches wide.

But it was Lazio who took the lead on the night, and halved the deficit on aggregate, after 12 minutes.

Luis Alberto swung in a corner and Castellanos got up above Alex Sandro at the far post and buried his header past Mattia Perin.

The two goalscorers from the first leg, Dusan Vlahovic and Federico Chiesa, almost combined to equalise.

Chiesa teed up Vlahovic to prod home from close range but his effort was saved by Christos Mandas.

Juve midfielder Manuel Locatelli was dealt a personal blow when he was booked for a foul on Nicolo Casale which means he will miss the final.

Castellanos should have levelled the tie two minutes before half-time when he found himself one-on-one with Perin.

But the Juve keeper came out quickly and was able to make a fine save to preserve the lead.

However, the Argentinian made no mistake three minutes into the second half after he was played in by Luis Alberto.

Castellanos used his strength to burst between two defenders before tucking his finish past Perin.

Vlahovic was denied a goal by a stunning piece of last-ditch defending by Adam Marusic, who slid in to block as the striker looked certain to tap in Weston McKennie’s pull-back.

But Massimiliano Allegri’s substitutions had an immediate effect after Timothy Weah’s cross-shot was tapped in at the far post by Milic with seven minutes to go to send the 14-time winners through.

Lautaro Giannetti dealt Juventus’ Serie A title hopes a potentially fatal blow as he grabbed the only goal of the game to earn a stunning 1-0 win for struggling Udinese.

The visitors made the most of a sluggish performance from Massimiliano Allegri’s men, who still trail leaders Inter Milan by seven points having played a game more.

Arkadiusz Milik was guilty of wasting most of the home side’s good chances as Udinese held firm for only their second win in 13 Serie A games which moves them three points clear of the relegation zone.

Looking to bounce back from last week’s loss to Inter, Juventus looked unlikely to be duly troubled in a strong start which saw Andrea Cambiaso and Federico Chiesa come close.

Udinese goalkeeper Maduka Okoye was busy early on, saving well from Milik’s close-range header then denying Federico Gatti who should have done better from the edge of the box.

The visitors grabbed the lead against the run of play in the 25th minute when Giannetti bundled home the loose ball after a free-kick was flicked on by Thomas Kristensen deep into the home box.

Milik failed to reach a cross-shot from Cambiaso that caused panic in the Udinese box and it was clear the home side were once again missing striker Dusan Vlahovic, who was ruled out with a groin strain.

Milik headed straight at Okoye and it could have got worse for Juventus on the stroke of half-time when Sandi Lovric fired a speculative effort over from just outside the box.

Allegri’s men hardly improved after the break as they huffed forward for little reward, although they did briefly think they had levelled on the hour mark.

A corner was headed back for Milik to nod home but celebrations were cut short as the referee ruled the ball had drifted out of play in the course of the initial set-piece.

Chiesa rammed a 72nd-minute effort over the bar while Kenan Yildiz was inches from connecting with Cambiaso’s left-wing cross in front of goal as Udinese managed to hold on for a famous win.

Juventus stayed on course for a record-extending 15th Coppa Italia title with a thumping 6-1 win against Serie A strugglers Salernitana in Turin.

The Allianz Stadium fell into stunned silence in the opening minute when Chukwubuikem Ikwuemesi gave the visitors a shock lead.

But Juve hit back through Fabio Miretti and Andrea Cambiaso before the break and ran riot in the second half.

Daniele Rugani, Dylan Bronn’s own goal, Kenan Yildiz and Timothy Weah all added to the scoring and Massimiliano Allegri’s side will now face Frosinone in the quarter-finals.

Salernitana head coach and former Juve striker Filippo Inzaghi’s side made a dream start against his former club as Ikwuemesi struck the opening goal in the first minute.

The Nigerian striker pounced on an error in the penalty area by defender Federico Gatti and buried a low finish into the bottom corner.

Juve goalkeeper Mattia Perin then denied Salernitana a second as he made a flying save to keep out Junior Sambia’s shot from outside the box, which was destined for the top corner.

But the Bianconeri, showing seven changes from last week’s home Serie A win against Roma, rode the early storm and hauled themselves level in the 12th minute.

Cambiaso’s headed pass inside the area picked out Miretti, who converted with a low, left-footed effort.

Juve were awarded a penalty in the 18th minute by referee Davide Ghersini, only for VAR to rule Sambia had fouled Gatti outside the box and a free-kick was awarded instead.

Federico Chiesa and Rugani were both thwarted by Salernitana goalkeeper Vincenzo Fiorillo as Juve built up a head of steam and after going close again through Chiesa and Adrien Rabiot’s header, the home side took the lead.

Danilo reacted quickest on the edge of the six-yard box following a 35th-minute corner and teed up Cambiaso, who slotted home from close range.

Juve looked to extend their lead before the break, with Arkadiusz Milik’s thunderbolt and Miretti both forcing Fiorillo into further saves.

Salernitana’s task looked beyond them in the 54th minute when Rugani turned home a rebound after Milik’s header from a corner had been saved.

Juve made it 4-1 with 15 minutes remaining when substitute Kenan Yildiz’s shot was deflected in off Tunisia defender Bronn.

Yildiz added Juve’s fifth in the 88th minute with a superb solo effort and Weah lashed home a low shot from outside the box to complete the scoring in the first minute of added time.

Andrea Cambiaso struck with virtually the last kick of the game as Juventus climbed to the top of Serie A with a 1-0 win over Hellas Verona.

Moise Kean had earlier seen two goals disallowed by VAR as Verona chased an unlikely point in their battle against relegation.

Verona have never won away at Juventus in Serie A history and that record now stands at 33 matches, following a heartbreaking defeat.

Juve thought they had taken the lead in the 13th minute when Kean, after 10 league games without a goal, spun his marker 25 yards out and launched an unstoppable drive past Lorenzo Montipo.

But the VAR took the play back to when Kean originally collected the ball before turning back on himself and adjudged him fractionally offside.

Kean was denied again moments later when his header from Manuel Locatelli’s corner was tipped over by Montipo.

The Italy striker, still aggrieved at having his goal ruled out, beat another couple of challenges on the edge of the box but, having been forced wide, he lashed his shot off target.

Verona weathered the storm and fashioned a couple of half chances, but Michael Folorunsho and Milan Djuric fired wide while Wojciech Szczesny saved from Federico Bonazzoli just before the break.

Kean squandered another presentable chance early in the second half when he planted a free header wide.

His frustration grew to boiling point when he glanced a superb header home after a sweeping Juve attack, only for VAR to haul it back for a foul by the forward in the build-up.

The 23-year-old was promptly booked for hurling the ball away after another decision went against him.

An 11th match without a goal came to an end on the hour when Kean was replaced by Federico Chiesa.

The substitute was immediately in the thick of the action, forcing Montipo to acrobatically tip his shot over the top.

Chiesa had his head in his hands moments later when he received a cut-back from the byline, only to see his first-time shot from 10 yards cleared off the line by Davide Faraoni.

Federico Gatti tried his luck from 25 yards, but his fierce drive flew wide and teenage substitute Kenan Yildiz lifted a glorious chance too.

But Juve’s moment came at the end of six minutes of stoppage time when Arkadiusz Milik’s header came back off the inside of the far post and Cambiaso smashed in the rebound.
