Japan’s shock 1-0 loss to Costa Rica threw the group wide open, with Germany last in the pool with one point but due to face the Ticos in their final game.
Flick’s team can climb up to second spot to qualify for the knockout stage if they beat Costa Rica and Japan lose to Spain. Alternately, a handsome Germany win could see them progress even if the Blue Samurai draw.
“In these matches, there are things to do better, but I am very upbeat,” Flick told reporters.
“Maybe, this result will help us improve morale for the future. I liked the mentality of the team during the 90 minutes and that’s what we have to show.”
Antonio Rudiger had a first-half header disallowed, before Alvaro Morata put Spain ahead on the hour from Jordi Alba’s pass.
But Die Nationalmannschaft leveled the game up with Niclas Fullkrug rifling home an 83rd minute strike.
“The team maintained a great level,” Flick said. “I am very satisfied with the mentality and the team’s work today. This was a match on a high level.
“Those are things we want to see from this team, but this was only a first step. We want to see (more in the) next match and create the conditions to go through.
“Spain are a great team with many young players, some experienced players, they’re technically very refined. They started well, but we pushed against them.
“We were also able to defend well, we went in hard. But this is an opponent who plays so freely with great qualities, they are difficult to defend against, and we need to work on that and improve in defence.”
