Lautaro Martinez fired Inter Milan back to the top of Serie A with the only goal in Sunday’s dramatic 1-0 win at Fiorentina, as depleted Napoli played out an uneventful goalless draw at Lazio.Argentina forward Martinez glanced home the decisive goal in the 14th minute of an action-packed contest in Florence in which Nicolas Gonzalez wasted a late penalty for the hosts, who had Inter on the back foot for much of the game.However it was a clash which ended with Inter one point ahead of Juventus, who were held by Empoli on Saturday, with a game in hand ahead of the two title rivals meeting at the San Siro next weekend.”I can’t say anything to these guys because we’ve won 17 matches from 21, scored 50 times and let in only 10. I can only applaud them,” said Inter coach Simone Inzaghi to DAZN. “Next week will be a match between two teams who play very high quality football… Juve are a team that you really need to face in your best form.”Martinez is now on 22 goals in all competitions for the season, the Inter captain’s league tally of 19 in 21 matches putting him way ahead in the division’s scoring charts.Inter fans will have breathed a huge sigh of relief at the final whistle as the win was largely down to Fiorentina’s poor attacking, with bad decisions going forward the order of the day for Vincenzo Italiano’s side. The Tuscan outfit missed the chance to take fourth and the final Champions League spot off Atalanta and stay fifth, two points off the money-spinning top-four positions.Fiorentina thought they were set to snatch a point when Yann Sommer was penalised for punching M’Bala Nzola while trying to clear a speculative ball into the box. But star attacker Gonzalez, who returned from the bench after six weeks on the sidelines, rolled a dreadful spot-kick at Sommer, their third missed penalty of the season.”I’m disappointed that in matches like these we never seem to find that piece of play which can change the course of the match, or at least see that we not lose,” said Italiano to DAZN. “And we’ve got a sort of penalty curse which is starting to irritate me. It’s not good enough.”SERIE A – MATCHDAY 22Friday Cagliari – Torino 1-2 (0-2)/Viola 77 – Zapata 23, Ricci 45+3/Saturday Atalanta – Udinese 2-0 (2-0)/Miranchuk 33, Scammacca 45+1/Juventus – Empoli 1-1 (0-0)/Vlahovic 50 – Baldanzi 70/AC Milan – Bologna 2-2 (0-1)/Loftus-Cheek 45, 83 – Zirkzee 29, Orsolini 90+2 pen/Sunday Genoa – Lecce 2-1 (0-1)/Retegui 70, Ekuban 76 – Krstovic 31/Monza – Sassuolo 1-0 (1-0)/Colpani 31/Verona – Frosinone 1-1 (1-0)/Suslov 45+3 pen – Kaio Jorge 58/Lazio – Napoli 0-0Fiorentina -Inter 0-1 (0-1)/Martinez 14/Monday 22.45: (5.90) Salernitana (3.70) Roma (1.70)***odds are subject to change
