Vilanova expects 'dangerous' Real
Vilanova's side narrowly escaped defeat to Osasuna on Sunday as they came from behind to win 2-1, but Jose Mourinho's team were not as fortunate as they went down to Getafe by the same scoreline.
Asked whether Sunday's result would make Real more vulnerable or more formidable in the second leg of the Spanish Super Cup on Thursday, Vilanova was in no doubt the reigning La Liga champions would be harder to beat.
"(It will make them) more dangerous, yes, yes. That's normal, the same would happen with us," Vilanova told reporters.
"If we had not won in two or three games and we were playing at home, we would try to change the dynamic as quickly as possible.
"But in themselves Madrid are already dangerous with the number of players they have, and in the (Santiago) Bernabeu. It is impossible to think about going to Madrid and having an easy game.
"They are very good. You just have to look at what they did last year."
Barcelona will take a 3-2 lead to the Santiago Bernabeu on Wednesday after Pedro, Lionel Messi and Xavi netted at Camp Nou.
However, Vilanova admitted that while it would be nice to lift some silverware by winning the Super Cup, he does not believe the result will have much bearing on the rest of the season.
"(It is) better to win it than not win it, but I don't think it marks the season. We have had three games and thinking that the winner of the Super Cup is going to win all the titles to come... I don't think so. There is so much ahead," he said.
"We all know Madrid will win many games and points. It is too much to analyse with only two match days (in La Liga)."
The 42-year-old also revealed that new signing Alex Song could be in line to make his debut in the fixture.
"He (Song) has only had a week. He has a few mechanisms to learn obviously. We will see if he gets a few minutes," Vilanova said.
