Sevilla coach Vincenzo Montella was delighted with their Copa del Rey win at Atletico Madrid on Wednesday night.
Sevilla won 2-1 in the first-leg of their tie with goals from Jesus Navas and Joaquin. Diego Costa was Atletico's goalscorer.
Montella stated: "It was a very positive afternoon. When a new coach arrives, we all have to get used to it. There are new concepts. We had the need to play more compact. It is a very important victory against one of the best teams in Europe.
"This has to be the start. I think it's a good step forward in conviction. It should give us confidence to build something important.
"Today we have risked a little more. It is important and it is what I want."
