The Germans recorded a 2-0 win in Turin this evening to book their place in the last four, with Robben hailing the outcome as an "amazing result".
"If you win away 2-0 in Turin here I think that's an amazing result because they are unbeaten for I don't know how many games and they are so strong at the back," BBC Sport quotes him as saying.
"Even more, if you dominate the game in the second half as we did, it is a great performance. We would like to be kept apart from Borussia Dortmund in the semi-finals but we don't have a choice and it comes out how it comes.
"It going to be a big one, and the semi-finals have maybe the four best teams at the moment."
