"We can't change what's happened in the other games and we should not think about any of the other teams," said the Spaniard.
"All we can do is concentrate on ourselves and work harder. As soon as we win away, I'm sure you will see a difference.
"When we win an away game, the difference will be massive in terms of the confidence of the players. We have shown consistently we have the quality at home, and there are times when we have played well away but have had problems scoring goals."
