"It was a fairly easy evening," said the Dutchman. "For the first-half we had no problems, after the break Barcelona gave us a few dangerous moments: a free chance for Thierry Henry and a shot from Samuel Eto'o."
On Cristiano Ronaldo's penalty miss, Van der Sar added: "That was a great opportunity to lead early on, but I think the penalty came a little too soon.
"After three minutes you're still not really in the game. Cristiano almost never misses, but in ten penalties you shoot there's an average of about eight being converted. Of course you hope that he misses one if you're already 3-0 ahead. But Ronaldo has already done good things throughout the season and to get a 0-0 is simply a good outcome."
