Valencia striker Paco Alcacer admits Spain's Euro2015 defeat to Slovakia was frustrating.
Alcacer struck in the 2-1 defeat.
He said: "I think they produced nothing in the first half. Only a free-kick goal. And then we wanted to go for the win after drawing level and their counter-attack made it 2-1. We wanted to score a second more than anything and a slip back toward defence cost us."
About his appearance, which he once again marked with a goal, he said: "When I have the opportunity I try to take advantage. There are enough matches left to allow us to make up for this result - we have to think that this result will help us to correct errors."
