Fiorentina and Napoli will meet at Stadio Artemio Franchi on Sunday afternoon, as the hosts look to continue their improvement under Paolo Vanoli.Fiorentina has three points from four Serie A matches, while Napoli has six after winning twice and losing twice.Verdict: Over 2.5 goalsBest odds: 47/50Bookmaker: 1xBetFiorentinaFiorentina has responded well to Vanoli’s return.Fabio Grosso lost his job after three straight league defeats, and the change has brought two immediate wins. Fiorentina beat Venezia 4-2 before defeating Pisa 3-0 in the Coppa Italia.Franco Mastantuono was the main attacking threat against Venezia, scoring a hat trick. Mateo Pellegrino also found the net after coming off the bench.Pellegrino scored again against Pisa, with Wilfried Gnonto and Pedro Goncalves adding the other goals. That gives Vanoli several attacking players pushing for a place.The defensive record still needs attention. Fiorentina has conceded 11 goals in four league matches, allowing at least two in every game. The clean sheet against Pisa is encouraging, but Napoli should provide a much tougher examination.The hosts have good reason to attack after scoring seven times in two matches. The danger is leaving too much space behind their midfield when possession changes hands.If Fiorentina commits both fullbacks forward, Napoli should have opportunities to play into those gaps. That makes another open match a reasonable expectation.Fiorentina Team NewsFabiano Parisi remains unavailable as he recovers from an ACL injury.David de Gea should start in goal. Radu Dragusin and Luca Ranieri are options in central defense, with Alex Jimenez and Viery available at fullback.Nicolo Fagioli and Arthur Atta should return after being rested against Pisa. Cher Ndour and Christ Inao Oulai also give Vanoli options in midfield.Mastantuono should keep his place in attack. Beto and Pellegrino are competing to lead the line, while Gnonto and Alieu Njie offer different choices on the left.Pellegrino’s recent goals make him difficult to leave out, even if Vanoli starts with Beto again.NapoliNapoli has had a mixed start to the season.They opened with a 2-0 win over Genoa, then lost 2-1 to Como and 3-2 to Inter. A 1-0 victory over Bologna brought them back to winning ways in the league.Stanislav Lobotka scored the winner against Bologna. It was a welcome result after the defeats in Serie A and a 1-0 loss to Arsenal in the Champions League.Those last two matches show that Napoli can be involved in tight games, which is the main concern for an over 2.5 goals selection.Fiorentina’s recent matches point toward a different kind of contest. The home side has started scoring more freely, while its league defense continues to give opponents chances.Napoli should try to get Rasmus Hojlund running behind that defense, with Kevin De Bruyne looking for early passes into his path. If Fiorentina pushes up to press the midfield, those runs could become especially important.Recent meetings have also produced goals. Napoli has won the last four league matches between the clubs, and all four finished with at least three goals.Napoli Team NewsAlex Meret, Alessandro Buongiorno, Luca Marianucci, Scott McTominay and Alisson Santos are among Napoli’s absentees. Vanja Milinkovic-Savic is expected to continue in goal.Frank Anguissa trained separately on Friday, while Leonardo Spinazzola missed the session with a minor hamstring problem. Both need further assessment before the trip to Florence.Giovanni Di Lorenzo, Amir Rrahmani and Rafa Marin should feature in defense. Mathias Olivera is an option on the left if Spinazzola cannot play.Billy Gilmour, Lobotka and De Bruyne are likely to form the midfield, with Matteo Politano and Antonio Vergara supporting Hojlund.The injuries reduce Napoli’s choices, especially when they need to change the game from the bench.Fiorentina vs Napoli key factors to considerFiorentina has won both matches since Vanoli returned.Fiorentina has scored seven goals across those two victories.Fiorentina has conceded 11 goals in four Serie A games.All four of Fiorentina’s league matches have produced over 2.5 goals.Napoli has scored in every league match this season.The last four league meetings between these clubs have all produced at least three goals.ConclusionFiorentina’s attacking improvement gives this match a good chance of producing goals. Vanoli has several players in scoring form, and the hosts should approach the game with more confidence after consecutive wins.Their defensive problems are still a concern. Napoli has enough quality in attack to punish the spaces that Fiorentina has been leaving in league matches.A cautious opening is possible, particularly after Napoli’s recent low-scoring games. Once either team scores, the need for the other to respond should create more room for both attacks.Over 2.5 goals is the best selection.Verdict: Over 2.5 goalsBest odds: 47/50Bookmaker: 1xBetThe post Prediction: Fiorentina vs Napoli appeared first on SoccerNews.
