Lazio, Udinese, and Milan have the same points only Lazio is superior on goal difference. just like you too, I really salute the developments that occur in Lazio, they look amazing. ciro immobile closed Lazio's win by scoring 1 goal in the 91st minute, he is the top scorer in Serie A with 6 goals.
It's surprising to see the ranking of the class so far. This was beyond my guess before the season started. Juventus, Inter, Milan are off the beaten track. They were missing from the top 3.
Even Roma, who has a fairly good transfer, is playing unstable. It seems that the transfer market later should be used to improve the team's situation. Otherwise it is even possible that Inter, Milan, and Juventus will not qualify for the UCL next season.
