The Blaugrana are currently considered by many to be the best team in the world, and the Catalan giants have certainly lived up to their expectations this season; Barcelona have amassed an incredible 65 points from 24 La Liga games and have lost only once in all competitions since the start of the year.
For Milan however, this season has been one of transition; the Rossoneri parted ways with key players Zlatan Ibrahimovich and Thiago Silva during the summer and struggled during the initial stages of the campaign, but Massimiliano Allegri's men have shown signs of getting back to form in recent times and have won a respectable 17 points in their last seven games.
Unsurprisingly, many have tipped Barcelona to ease past Milan and progress to the quarter-finals of the Champions League, but Roura warned that nothing was set in stone yet and revealed the Rossoneri's strength when playing at home worried him.
"Milan are one of the most successful teams in Europe and they're playing at home," Roura was quoted as saying by the official Barcelona website.
"They are a different team, they play a different way, and we'll have to wait and see how they behave.
"But we have always found it hard against them and have had some tough times in the San Siro.
"There's no sense talking about favourites because Milan are always frightening at home"
Roura also admitted that his side needed to improve on their defending, but claimed that everybody in the Barcelona dressing room was looking forward to the game.
"We still normally score more goals than the opposition," Roura added.
"But I do agree that we need to work on certain aspects and there is room for improvement in that respect.
"We haven't played a Champions League game for some time and of course players at this level look forward to these games.
"We're all happy to have got here, and the players are very much up for it."
Both Milan and Barcelona were 2-1 victors over the weekend in their domestic league, with the Rossoneri beating Parma and the Blaugrana overcoming Granada.
