It's impossible for Lazio to win the title without even beating other top contenders. There are many title contenders in serie a and beating them all is a must for Lazio. The winner of serie a averagely needs around 90 points to take the title, wihch is hard to do without beating the big clubs. I know there's no knockout in the league. But, it's vital to farm three points from the big clubs. It stops other clubs from getting a chance at the title.
Lazio had already 3 defeats comparing to Inter for example which has only one. The draw could be related to a temporarily failure of the attack line but the defeat means that this failure touched also the defence line which might be more serious.
I don't feel that this version of Lazio could pick the league title but definitely the other teams in Serie A aren't any better since the difference between them is only one point.
At least, with the points gap still very close like this, then of course every team has a chance to be at the top of the standings.But even so, of course there is still no guarantee for them to get the Scudetto, because the competition for the Scudetto in Serie A at thismoment becomes very tight. Also, about Lazio, the fact that Lazio in the last few seasons has always consistently at least managed to finish in the top seven.
With achievements like that, then of course Lazio also has a chance to get good results this season, and Lazio cannot be underestimated at all. Because of course, Lazio are a team to watch out forthis season, because they have performed well so far this season, Lazio are also currently at the top of the standings in the Europa League.
