Champions League has given them the edge in the tie.
The Red Devils took the lead in at the Bernabeu through Danny Welbeck, but were pegged back by former hero Cristiano Ronaldo.
After netting what could be a vital away goal, van Persie feels that United have moved ahead in the race for a spot in the quarter-finals, but he also insisted that there is plenty of work left to do:
“Slightly.” He responded when asked by Sky Sports if the result has put them on top in the tie:
“But at this level I don’t think these kinds of teams really care whether they are home or away.
“We don’t really care and they don’t really care. It’s just half-time now and we’ll be ready for the second half.
“There were chances for both sides and it was a great game to watch,”
The Dutchman had a few opportunities to hand the Premier League leaders a shock win in Spain, but was unable to convert.
He admitted that he was frustrated at being incapable of giving his side a shock aggregate lead, but that the result is still a positive one:
“We had a couple of good chances but if you had said before the game we would draw 1-1 then most of us would have taken it.”
Welbeck headed a Wayne Rooney corner past Diego Lopez to give United the lead on 20 minutes, but Ronaldo netted shortly after to level the scores.
