If you look at the history of Roma's strength, Udinese should not be an important problem and should be easy to beat, but all of this must use a good teamwork strategy.As long as Roma can do that, victory will be easy to obtain. Roma has many great players, and of course Roma must try to get into the top five at the top of the standings.
AS Roma is surely better, they are much stronger if we look at their squad quality. Basically AS Roma is one of the top team in Serie A, they are ideally in the top 5 and joining the race for the title. But sadly AS Roma is only in the 7th place, they have no chance to join the race of the title. The main problem of AS Roma is they can't play consistently, they played underperformance.
Against Udinese, ideally AS Roma will win the match easily. But AS Roma often gets a surprising result. They sometimes were defeated by small teams, or got a draw against mediocre teams.
