“With the four goals we were in a good moment. But we want to be competitive in 90 minutes and I think the last 20 minutes we conceded chances. We need to improve this.

“Our disappointment today is the two goals conceded. I think the first 60 minutes were very good. We’re going to continue progressing with that idea. There were a lot of positives things in the game.”
