ROME, April 6 (Xinhua) -- Mattia Destro scored his first Serie A hat-trick as Roma beat Cagliari 3-1 on Sunday to make sure of a place in UEFA Champions League next season.
The win puts Roma 21 points clear of fourth-placed Fiorentina with six Serie A games left, and Rudi Garcia's side have Destro to thank for his inspiring performance.
Destro fired his first goal just after half an hour thanks to good work from Gervinho, and his second came 12 minutes after the break to finish off a superb counter-attack.
He completed his hat-trick after beating a offside trap with 17 minutes from time. Though Mauricio Pinilla scored late on from the spot, it wasn't enough to deny Roma a first win in Cagliari since October 1995 - excluding a 3-0 win they were awarded last year without playing.
Napoli's chances of chasing are fading away as they are 12 points adrift of the Rome side after suffering a 1-0 defeat at Parma.
Napoli head coach Rafa Benitez confessed his side won't get beyond third and are missing something.
"We are all disappointed to lose a game that was under control in the first half and at the end of the day Parma only had one shot on goal. We had a great chance and we missed it," he said.
"You can tell we are missing something. We won't finish second, as Roma win those games that we do not. This is the reality and we have to work every day to improve, but in the meantime we can lock down third and prepare for the Coppa Italia Final," he said.
The result means Juventus can secure a top-two finish, and an automatic Champions league spot, with victory over Livorno on Monday, while Parma are now level on points with Inter who are in the final Europa League place.
Fiorentina rebounded from two winless games by beating Udinese 2-1 and strengthened their hold on the UEFA Europa League places.
Juan Cuadrado's sixth league goal of the season put the Vincenzo Montella's side 1-0 ahead in the 25th minute and Gonzalo Rodriguez doubled the advantage from the spot in the second half.
Udinese caused late panic with a Bruno Fernandes strike but Fiorentina held on to move within nine points of third-place Napoli.
Catania sacked Rolando Maran as head coach following their 2-1 home defeat to Torino.
The hosts got off to a perfect start as Gonzalo Bergessio scored for them after two minutes, but Alexander Farnerud and Ciro Immobile struck late on to condemn the league's bottom side to a fifth straight defeat.
The loss resulted in Maran's second sacking of the season by Catania.
Despite one man less in the final 30 minutes, Lazio beat Sampdoria 2-0 at home to move to within two points of Inter.
Antonio Candreva gave Lazio a lead just before half-time but they were a man down within 12 minutes of the second half after Lucas Biglia was sent off for his second booking.
But it didn't derail Edoardo Reja's side, who clinched their second consecutive win with a Senad Lulic goal.
Atalanta's six-game winning streak was snapped when they lost to lowly Sassuolo 2-0 at home.
Nicola Sansone struck in each half to give Sassuolo a real chance of survival, who are now three points from safety.
