Roma manager Rudi Garcia has admitted that his team are in for a tough match against Serie A rivals Juventus this weekend.
The two teams have both won all of their league fixtures this season and lead the way at the top of the table.
"It is a big test, even if it is only on the sixth round of the season," Garcia told Le Figaro.
"There are still a lot of points up for grabs. It is too early to make a final judgement.
"We know that this is a top team but I think that we are going to demonstrate that we also are."
Roma came from behind to earn a 1-1 draw against Manchester City in the Champions League on Tuesday evening.
