Goals from Gareth Bale, Gylfi Sigurdsson and Jan Vertonghen were enough for the Lilywhites to comfortably beat Inter 3-0 in the first leg at White Hart Lane.
Despite Spurs' three goal advantage, Friedel admits he is wary of Inter's attacking prowess and believes his side needs to score goals in the second leg at San Siro in order to secure qualification into the quarter-finals of the competition.
"They are still in the match at 3-0 but we'll go out there with the attitude to score," Friedel was quoted as saying by the Sun.
"And if we get that decisive away goal, they'll have a mountain to climb.
"Away goals are so important and getting a clean sheet is too, as was the third goal before going to the San Siro.
"Before the game we'd have taken 3-0 so we were very pleased - but it's only halfway in the tie."
Spurs defender Michael Dawson echoed Friedel's sentiments and expressed his belief that Inter would go all out to avenge the humiliating first leg result.
"We all know how tough it is in the San Siro and one thing is for sure, they won't lie down," Dawson told the official Spurs website.
"There is a lot of pride at stake and I'm sure they will be hurting after losing 3-0 like they did at the Lane. We have to be ready for that.
"We're in a great position, don't get me wrong and we now have to go there, do a professional job and if we do that, we'll be okay. It won't be a walk in the park though, that's for sure."
Inter beat Spurs 4-3 the previous time both teams met in a competitive game.
