America - bidding to match Cruz Azul's record of six Champions League titles - welcome Montreal to the iconic Estadio Azteca in Mexico City on Wednesday on the back of a 4-0 humbling at home to Queretaro over the weekend.
The reigning Liga MX Apertura champions were put to the sword by Queretaro on Saturday, with Brazilian legend Ronaldinho completing the rout courtesy of a late brace.
However, Klopas is not paying attention to America's recent results heading into the midweek showdown, which is expected to be played in front of a capacity crowd nearing 105,000 supporters.
"Regardless of outcome of [Saturday's] game, they're going to be very motivated to play because it is a final," Klopas said.
"I don't take too much away from the game from the other night. For me, some of the things I needed to see – because I've watched a lot of their games – I saw [on Saturday].
"But for sure, we have to expect a different team, a different mentality and approach on Wednesday."
"They have some issues at the back because of the suspension to Goltz, and Alvarado with the yellow cards," Klopas added.
"But Samudio played, he's very experienced, good left back. They have [Pablo] Aguilar, the right side guy. So it's just with one centre back, what they are going to do. But we know their team. I don't think there’s going to be any surprises."
While America, who boast a tournament-high 3.75 goals-per-game ratio, have struggled for consistency, the Impact's form is cause for concern.
"We have to start the game in the best of ways, and everyone has to get ready, get in their zone," said Montreal centre-back Laurent Ciman.
"With that in mind, we've seen that we can keep it at zero at the back. We must not be afraid of that team.
"Of course, they're the favourites. They're playing at home. We have to feel free when we get there and play football the way we know how."
