"We have a depth in our squad and I think you could see that in this game - because one or two players are out injured we don't have to change or drop in performance."
Michu, Jonjo Shelvey and Pablo Hernandez were the goalscorers as Swansea put in an impressive performance at the Madejski Stadium and the Dane found the result encouraging.
"[It was] another step forward against a good side, who I think are one of the favourites to get back to the Premier League," he enthused.
"It was a very good result, scoring goals and not conceding any goals once more, so that's important as well. [We are] playing in the first leg at home it's so important not to concede any goals."
