"Everyone feels that we are capable of turning things around," he Spanish television channel Cuatro. "Many hours have passed and our spirits are higher.
"We now have to win our next two games, which won't be easy, but is within the realms of possibility. We are searching for the best possible preparation and we are trying to make sure the players are not sad. We have to enjoy ourselves."
