Juventus coach Andrea Pirlo was left upset with their 2-2 draw against Roma.
Adrien Rabiot was sent off with Roma 2-0 ahead, but Cristiano Ronaldo's brace earned Juve the point.
"We faced two completely different teams this season, so I knew our approach would be totally different to the one against Sampdoria," Pirlo told Sky Sport Italia.
“It was a step back in terms of performance, but this is a work in progress and we haven't had an opportunity to play pre-season friendlies to test these things out.
“It was ultimately a point gained, as we were a goal down twice and then down to 10 men, while we have some players like Arthur who haven't really played for six months.
“We wanted to make the most of one-on-one situations, as we knew Roma would attack in numbers, but it didn't go quite the way we hoped. It was always going to be tough against an organised team.
“We tried to keep the midfield lines tight to not allow space for the trequartista. At times it worked, at times it didn't, but we are having to test all these situations during a match, seeing as we didn't have pre-season friendlies."
