Assistant manager Jordi Roura insisted “beating Milan 4-0  is not normal for anyone, not even Barcelona.”
Roura was on the bench, as Coach Tito Vilanova is in New York undergoing treatment for throat cancer.
The Spaniards fought back from a 2-0 defeat in the first leg to reach the Champions League quarter-finals.
“Beating Milan 4-0 is not normal for anyone, not even Barcelona. They are a great team and made life very difficult for us. It was certainly not normal for us,” Roura told Sky Sport Italia.
Lionel Messi had never scored from open play against an Italian club, but this evening bagged a brace.
“Messi received criticism in recent days, as all our players did, but today we showed that we could react.
“He has a very special way of playing football and the fact he plays like this allows us to have these victories.
“It is a very important win for Vilanova. He is fortunately doing well and completing his recovery in New York, so will soon be back. We are happy that we progressed in the Champions League so that we can welcome him back with open arms.”
