There are four teams with a realistic chance of filling the three remaining Champions League spots, while at the other end of the table 10 teams are still in danger of going down to Serie B.

Here, au.fourfourtwo.com looks at the runners and riders in the European and relegation battles:

Champions League

Roma (2nd, 69 points): Holding a 10-point advantage over AC Milan in third with four games to go, Roma have all but filled the second automatic Champions League berth.

AC Milan (3rd, 59 points): Milan are on an unbeaten run in the league stretching back to the 2-1 derby defeat to Inter on March 11. That loss was only their second setback in 24 Serie A games. They face UEFA Cup-chasing Fiorentina at the San Siro in an otherwise straightforward run-in.

Lazio (4th, 58 points): Lazio have won only once in six games, although they were unbeaten in 11 before that, and their last four games are a mixed bag. Inter could be in charitable mood, but Siena and Parma are still fighting for their Serie A lives. Livorno should not be too taxing, however.

Palermo (5th, 52 points): Palermo's 2-1 win at Livorno at the weekend was their first since February 2. That dismal run, which cost coach Francesco Guidolin his job, has left their chances of making one of the Champions League qualifying spots hanging by a thread after looking certainties for that spot earlier in the season. With Siena and Roma still to play, they must be considered outsiders to pip Lazio or Milan.

Relegation spots

Ascoli (20th, 20 points): Only three wins all season suggests that Ascoli are going back to Serie B after two campaigns in the top flight. They are 13 points from safety and need to win all five of their remaining games and hope, somehow, other fixtures go their way to stand any chance of survival.

Messina (19th, 25 points): Messina are only marginally better off than Ascoli and are eight points away from the safety of 17th place. Their final four fixtures of the season are incredibly tough too, facing European chasers Roma and Fiorentina, relegation rivals Parma as well as a visit by champions Inter.

Chievo (18th, 32 points): Chievo have been in and around the drop zone all season and face a tough ask to clamber out of the bottom three. Their next fixture is against Parma, the form team among the relegation candidates, and also have to play Reggina and Catania, plus Ascoli, with all three desperate for points at the bottom.

Torino (17th, 33 points): With two wins in 18 games, Torino have displayed nothing other than relegation form for much of the season. Wins against Ascoli and Livorno in the coming weeks look to be their best chances of picking up the six points that could be enough to keep them safe.

Cagliari (16th, 34 points): David Suazo's 13 goals put him among the sharpest shooters in Italy and he is Cagliari's best hope of getting out of the mire. The club's remaining fixtures are not too harsh, either. Udinese and Ascoli are beatable, while Roma could have second place sewn up by the time they visit Stadio San Elia.

Siena (15th, 34 points): Siena could yet live to rue the single-point deduction they received earlier this year for missing a tax deadline. Fourteen draws this season is the highest number in the league and the failure to turn these into wins has seen them in dire straits. They have four tough games, too, with Atalanta, in ninth, the lowest-placed team they face.

Reggina (14th, 34 points): Reggina have spent the season trying to overcome an 11-point penalty given to them for match-fixing. As such, their current league position does not reflect where they should be in the table. Demotion is unlikely.

Parma (13th, 35 points): Claudio Ranieri's arrival as coach in January did not prompt an immediate upturn in their fortunes, but the Gialloblu have now hit form at just the right time. Five wins and a draw in their last seven games has lifted them clear of the bottom three and safety is in sight. Wins over rivals Chievo and Messina should be sufficient to ensure another season in Serie A.

Catania (12th, 36 points): Without Gionatha Spinesi's 14 goals, Catania would surely be in a far worse position. But they have him and a further five games to accrue the four points that ought to keep them up after what has been a difficult season on and off the pitch. Home victories over Ascoli and Chievo seem the best opportunity to surpass the 40-point total.

Livorno (11th, 36 points): So tight is it at the bottom of Serie A, that even 11th-placed Livorno are not safe. But as with Catania and Cagliari, they have a goalscorer to rely on. Cristiano Lucarelli has 18 goals, only three behind Francesco Totti in the race for the capocannoniere, the accolade awarded to Serie A's deadliest marksman. Despite a tricky run-in, his goals should keep Livorno up.
