Barcelona fullback Jordi Alba concedes Spanish "heads dropped" during their World Cup thrashing by Holland.
Spain need victory over Chile to stay in the mix of reaching the knockout phase.
"They put five goals past us, which is something I don't think anyone was expecting. We were the better team in the first half, but after the break everything went against us. Nothing came off for us, our heads dropped after the third goal and we paid the price," said Alba.
"We have to go all out against Chile to get the win. This is going to make us much stronger; the team is more united than ever. Our aim is to get through to the next round and we are going to try to do so."
