The Serie A side easily dispatched of Al Ain 5-0 in their tournament opener as Wydad went down 2-0 to Manchester City.
Despite losing to the English Premier League side, Wydad showed enough to prove they will be no walkovers, explained Tudor, who only took up the post as Juve boss in March as a replacement for Thiago Motta.
The Old Lady will secure a spot in the knock-out rounds with victory in Philadelphia on Sunday.
Ahead of the game, Tudor said on TMW: "It's a different opponent, we're playing at a different time. We've prepared to the maximum, like always. It's an important match against a quality team and we will have to give our best going full throttle for 90 minutes."
The match kicks off at 13:00 local time, with high temperatures expected, but Tudor says the heat will effect both teams.
"We have to prepare to face it, but it will be the same for both teams, and then we will have to forget about it, to focus on what we have to do," he explained.
"Wydad could have scored two goals in the first half against City. Each game is a test in itself. It's impossible to make comparisons between one game and another. Each game has its own particularities."
