Roma performance is not bad, they have improved. I was surprised that Juventus could not win roma . Roma has improving Much better than in the last season.
In this case it is not so surprising because Juventus' performance has decreased in the last two seasons, even they were only able to finish in 4th place in the last two seasons. While Roma, at least last season has started to look when they returned to the Europa League after failing the previous season.
The season has just start, there will be many surprises from Juventus or Roma. We'll see how these two teams face the tight competition in Serie A and maintain their respective positions.
