Antonio Conte felt Inter were hard done by as their Scudetto ambitions suffered a blow with a 2-1 defeat at Sampdoria. 

Alexis Sanchez missed a first-half penalty before Antonio Candreva converted from the spot for the hosts at the Stadio Luigi Ferraris. 

Keita Balde doubled Sampdoria's advantage in the 38th minute and, although Stefan de Vrij reduced the deficit and Romelu Lukaku - short of match fitness - came off the bench, Inter were unable to pull level. 

Milan host champions Juventus in a mouth-watering San Siro clash later on Wednesday, where victory would increase the Rossoneri's advantage over Inter at the summit to four points. 

The result halted an 11-match unbeaten run for Conte's men and he refused to be too harsh on his players after they failed to overcome a chastening first half. 

"We found ourselves going from the missed penalty to having a penalty against us. There was this one-two from Sampdoria that clearly created some difficulties for us," he told reporters. 

"At the same time, the team was doing well, in the first few minutes they created a lot of scoring situations. Sometimes you lose games you deserve to lose, other times there are situations where you can score and you don't." 

Despite those missed chances and struggles in attack for Lautaro Martinez, Conte refused to blame Lukaku's recuperation from a thigh strain for Inter falling short.

"It wasn't the first time we played without Romelu, we know that he is a player with certain qualities, but he wasn't 100 per cent and you saw it when he came on," he said. 

"Sorry because I think we deserved something more." 

Christian Eriksen was also introduced from the bench, despite being told he can leave Inter this month. 

"I always try to exploit the players according to the situations that arise and I am at the club's complete disposal on every decision," Conte explained. 

"I get to work, as I have always done since I have been at Inter, but every decision will always be shared." 

Inter return to action with a crunch clash against third-placed Roma on Sunday.

Antonio Conte called on Arturo Vidal to improve after conceding a penalty that gave Inter brief concern in their 6-2 win over Crotone.

The Nerazzurri were ultimately comfortable victors at San Siro on Sunday as Lautaro Martinez scored their first perfect hat-trick since Mauro Icardi's against Atalanta in March 2017.

However, Inter had been level at 2-2 at half-time following Vidal's needless error.

After Martinez's first effort and a Luca Marrone own goal turned the match around following Niccolo Zanellato's Crotone opener, Vidal charged towards Arkadiusz Reca and stepped on his foot in the area to concede a penalty, which Vladimir Golemic converted.

Inter coach Conte was worried at that stage the setback might affect his side, looking to win an eighth successive league match for the first time since 2008.

But Vidal was replaced at the interval and an assured second-half display saw Martinez score twice more either side of an excellent Romelu Lukaku effort, before Achraf Hakimi completed the scoring.

Conte told Sky Sport Italia: "We did well to turn it around, then the naivety on the penalty could have created anxiety and nervousness.

"But we did well to get back on track and bring home another win.

"We had good answers today, also because we had started in the right way. Then there was this corner where they surprised us [for Zanellato's goal]."

The penalty was the only foul Vidal committed before his premature withdrawal, but he won just two of his five duels and Conte was not impressed.

"Arturo has important margins for improvement," Conte said. "He definitely needs to work. Keep your head down and keep working.

"Nobody is guaranteed a place here and he has to prove he deserves to play. He must do much better than what he is doing.

"From what we've seen so far, there are too many ups and downs, and we can't afford them. He knows this, he knows he has to train harder.

"Maybe when you play in big teams, sometimes this aspect takes a back seat. Here instead you have to raise the level, he knows that. We'll give him time."

Far more impressive was Lukaku, who created the first Inter goal for Martinez, had a hand in the next two and then scored the fourth before he hobbled off with an injury.

Having seen his outstanding number nine net his 35th goal in his 50th Serie A game, Conte will hope he does not have to face a spell without the striker.

Inter are in action again as soon as Wednesday, facing Sampdoria, and the coach was waiting to hear more on Lukaku's problem.

"He told me he had a small quadriceps strain," Conte said. "We'll see tomorrow if he's at risk for the Sampdoria game.

"We took him off straight away. I don't think it's anything serious."

Lautaro Martinez hit a perfect hat-trick and Romelu Lukaku sparkled as Inter defeated Crotone 6-2 at San Siro to turn up the heat on Milan at the start of 2021.

Inter moved top of Serie A at least until Milan's meeting with Benevento later on Sunday as they recovered from a testing first half to ease past their struggling visitors.

It was all square at the break after Martinez cancelled out Niccolo Zanellato's opener and was in close attendance for a Luca Marrone own goal prior to Vladimir Golemic's equalising penalty.

But Martinez completed his treble following the interval, while Lukaku, involved in the first four Nerazzurri goals, was also on target and Achraf Hakimi swept in the sixth in a fifth straight home win.

Only an apparent injury to the outstanding Lukaku put a slight dampener on a day that had started in laboured fashion.

Crotone struck first as a smart set-piece routine created an angle for Junior Messias to loft in a left-footed cross and find Zanellato all alone six yards out, able to head in via the post.

But Inter were level when Lukaku's excellent reverse pass set Martinez clear to fire right-footed beyond Alex Cordaz, and more fine work from the former Manchester United forward turned the game on its head.

Lukaku seized on Arturo Vidal's tackle in the midfield and fed Nicolo Barella, who was taken wide by a heavy touch but managed to cut the ball back for Marrone to stab into his own net in front of Martinez.

Vidal's next contribution was rather more rugged, however, as he stepped on Arkadiusz Reca's foot in the area to concede a spot-kick - awarded following a VAR review - which Golemic dispatched.

Martinez restored Inter's lead 12 minutes after half-time, keeping his cool on his left foot as Marcelo Brozovic prodded the ball on following a backheel from Lukaku, who got the goal he deserved soon enough, too.

The game's standout performer span away from Sebastiano Luperto and sold Cordaz a dummy to leave a simple finish, although he then indicated an issue with 15 minutes remaining and was quickly substituted.

Martinez remained on the pitch to nod in the rebound when Cordaz saved from Ivan Perisic, Lukaku's replacement, and Hakimi had the final say.
 

What does it mean? Your move, Rossoneri

Milan are the only remaining unbeaten team in Europe's 'top five' leagues but will have to maintain their pace to keep clear of Inter on this evidence.

The Nerazzurri have won five in a row at home in Serie A for the first time since 2018 and look a match for any opponent with Martinez and Lukaku in top form.

Landmark Lukaku looks the part

This was Lukaku's 50th Serie A appearance and his tally of 35 goals in that time has only been bettered by five players in the three-point era.

It was the front man's work as Inter's battering ram that was most impressive here, however, finishing with just a single assist from his only key pass but winning both his duels and holding the ball up brilliantly to create the space for Martinez to have seven attempts.

Marrone endures torrid time

Marrone's own goal under pressure from Martinez epitomised a dreadful outing for the former Juventus defender.

He might have found his own net again early in the second half and was a liability throughout despite weighing in with four clearances, three interceptions and a tackle.

Key Opta Facts

- Inter have won eight Serie A games in a row for the first time since December 2008.
- Inter have scored at least 40 goals in the first 15 Serie A games played for the first time since 1950-51 (45 in that case).
- Crotone have conceded at least six goals in a Serie A match for the first time in their history.
- Martinez's treble is the first perfect hat-trick from an Inter player since Mauro Icardi in March 2017 (vs Atalanta).

What's next?

There is no easing back into league action in 2021 as Inter are playing again as soon as Wednesday, visiting Sampdoria. Crotone host Roma the same day.
