The attacker has rued his side's defeat at the Maracana on Sunday, but is confident that they will recover from their loss
Fred gifted Brazil the lead after only two minutes of play before Neymar doubled the Selecao's advantage in the closing stages of the first half, with Fred making it three shortly after the break.
"The key was losing a goal in the second minute of the match. From that point onwards, our approach and our gameplan had to change. We failed to adapt to the situation and we lost our head a bit," Torres told Fifa.com.
"We didn’t know whether to push forwards or hang back; we were in a bit of disarray. To make matters worse, they scored again on one of their breakaways to make it 2-0 just before half-time.
"We were confident we could raise our game and come back, but we started badly again and let in a third goal. Things got worse, as we then missed a penalty and had a man sent off. It was one of those days when nothing goes your way, right from the start."
The Chelsea attacker then went on to stress this weekend's defeat was a mere slip-up and that Spain will be back to defend their title at next year's World Cup.
"This was just a blip against a team that played better than us. We’ve already experienced similar matches: we played badly versus England, Portugal and Italy," he added.
"Although they were friendlies and this was a final, it won’t change how we approach things in the future. All that remains is for us to congratulate the champions. Brazil were better than us and won the match fair and square.
"It’s confirmed something that we already knew, that it’s not going to be easy to beat Brazil on their own patch. That said, in one year's time we’ll be back here as world champions to defend what’s ours."
