Luciano Spalletti saw positive signs from his Napoli side despite a 1-0 defeat to Lazio on Friday.

Matias Vecino's stunning effort condemned the Serie A leaders to only a second league defeat of the season and their first at Stadio Diego Armando Maradona.

Despite the loss, which brought an end to an eight-match winning streak, Napoli retain a 17-point lead at the summit and Spalletti was happy with his side's desire.

"I expected such an attitude from the Biancocelesti, they are very compact and always move en bloc," he told DAZN.

"We made the choices in the worst way ever, but I saw a good attitude, the right application and desire, and these are the fundamental things."

Defeat for Spalletti came at the hands of a player he knows well, having managed Vecino during the pair's time at Inter, and he issued praise to his former midfielder.

"Lazio defended well, they were lucky on Victor Osimhen's header and we were naive about Vecino's goal. Then the ball found that corner," he added.

"But I congratulate Vecino, he is a great professional and a great footballer. Did he betray me? I wouldn't say, everyone has to do their job without thinking about the relationship that there was previously."

Lazio brought an end to Napoli's eight-match winning streak in Serie A with a surprise 1-0 victory at the Stadio Diego Armando Maradona.

Matias Vecino struck the only goal of the game in the second half with a thunderous effort from distance in a frustrating game for the hosts.

Solid defending from Lazio thwarted I Partenopei, who were largely limited to efforts from distance and struggled to break down the visitors.

Late chances did come Napoli's way though, Victor Osimhen hitting the bar and Kim Min-Jae's rebound brilliantly saved by Ivan Provedel as Lazio head coach Maurizio Sarri inflicted only a second league defeat of the season upon his former team.

Lazio almost stunned the home fans inside five minutes, Vecino flicking a header from Mattia Zaccagni's free-kick towards the far corner but Giovanni Di Lorenzo was on hand to make a crucial goal-line clearance.

First-half opportunities were limited for the hosts, Andre-Frank Zambo Anguissa having the first sight of goal with a drilled effort from distance that deflected off Sergej Milinkovic-Savic and whistled just over the bar.

Napoli's inability to threaten Provedel's goal continued after the break, Khvicha Kvaratskhelia spurning a free-kick in a dangerous position by firing harmlessly into the stands, before Piotr Zielinski dragged wide from just outside the box.

The deadlock was finally broken by the visitors after 66 minutes, Vecino unleashing a thunderbolt into the right-hand corner of the net to leave Alex Meret helpless.

Napoli came agonisingly close to an equaliser 11 minutes from the end, Osimhen heading against the crossbar and Min-Jae immediately seeing his own effort clawed off the line by Provedel.

Milinkovic-Savic came close to consolidating Lazio's win after striking the frame of the goal with a late free-kick, though it mattered little as the visitors held on for a important win in their hunt for Champions League qualification.

Serie A champions Inter saw off Roma 3-1 at San Siro on Wednesday to stretch their club-record winning home league run to 15 matches.

Antonio Conte's men had failed to beat Roma on home soil in the league since 2015, but they raced into a two-goal lead in this latest clash inside the opening 20 minutes.

Midfield pair Marcelo Brozovic and Matias Vecino both scored from clinical finishes before Henrikh Mkhitaryan pulled one back just after the half-hour mark.

Edin Dzeko hit the crossbar in the second half but Inter, who were crowned champions with four games remaining, rounded out the win through Romelu Lukaku late on to extend their unbeaten league run to 20 matches.

With the Scudetto already sealed, Conte continued with his rotation policy and two of Inter's recalled players linked up for the opener with 11 minutes played.

Matteo Darmian pulled the ball back from the byline and Brozovic fired a first-time finish away from Daniel Fuzato.

The Nerazzurri did not take long to double their lead through a well-taken Vecino strike following some good play from Lukaku to chase down a pass and wait for support.

Roma put five unanswered goals past bottom side Crotone on Sunday and they were back in this game thanks to Mkhitaryan's curled finish away from Ionut Radu.

The visitors almost levelled up 11 minutes into the second half when Dzeko turned in the box and arrowed a shot against the frame of the goal.

Bryan Cristante headed wide from a glorious position and Mkhitaryan volleyed another chance into the hands of Radu, but Lukaku sealed the points for Inter with a last-minute tap-in after being unselfishly teed up by substitute Achraf Hakimi on the counter.
