Lazio remains a difficult opponent for Cagliari, because Cagliari very often get defeated when playing against Lazio whether it's a home match or away. Although the average score that Lazio got when beating Cagliari was not a big score, but Lazio was very consistent in beating Cagliari. But even so, at least Cagliari, who is currently in the bottom zone of the standings, is also still able to play well but yes, unfortunately Cagliari is still not strong enough to be able to beat Lazio. At least, the 4th position of the standings is a race for three teams namely Lazio, Juventus and Fiorentina who still have a great chance to be in fourth position, but they are difficult to maintain that position because they are not so successful in maintaining consistent performance.
Lazio is quite solid in top four of Serie A and they shown their strong mentality to stay at the fourth position under big pressure of Juventus recent weeks. This position, last one in top four, is a favorite and most achievable position for any club that are chasing top four because three above positions that are held by Napoli, Inter Milan and Atalanta are farther and less reachable.
Lazio already shown their ability to defend their fourth position under pressure latest weeks, but their fight will continue in 15 more matches, and other clubs will not easily leave that valuable position for Lazio at the season ending.
Roma deserved a draw with their unrestrained pressure at the end of the match and their great desire, while Napoli was just trying to keep the winning score technically, and his majesty football often punishes for this. This does not detract from the fact that Napoli is Inter's main competitor for the Scudetto, although the team seems to have lost a player like Kvaratskhelia, around whom Antonio Conte wanted to form the team, but as we can see, they are still coping without the Georgian player.
Roma played well and deserved a draw against Napoli, but this draw can not help them to improve their points and rank in Serie A. Roma have 11 points less than Lazio, and above Roma there are many clubs too but they will not give up their fight to have a fourth position or at least higher rank in Serie A too early. With 15 matches left in Serie A, AS Roma can do many more things, improvements, get more points and a higher rank than their current one.
