La Roja are considered major contenders to win gold, but the former Real Madrid man is taking nothing for granted in light of the recent shock 2-0 defeat by SenegalSpain Under-23s coach Luis Milla insists that he not looking past the Olympic opener against Japan, claiming that his side will be sent packing if they switch off for just 10 or 15 minutes against their Asian opponents.
La Roja are considered one of the favourites for the gold and they are going into the game in Glasgow on the back of a morale-boosting 1-0 win over Mexico on Wednesday night.
However, they were defeated 2-0 by Senegal in their previous warm-up clash and Milla feels that particular result is of greater relevance.
"Japan will be similar in style to Senegal: very dynamic, very physical, but with forwards and midfielders who are playing at a high level in Europe," the former Real Madrid man told reporters on Friday. "They are going to be a team that is very well prepared.
"So, I'm thinking only day to day; the game against Japan is the most important game. If you have a poor 10 or 15 minutes, you're going home."
Spain also have Honduras and Morocco for company in Group D.
