The 61-year-old insists expectations must be realistic ahead of his side's second Group H fixture on Sunday
Algeria sit bottom of Group H after losing 2-1 to Belgium in their opening fixture - a game they were winning until the 70th minute.
And Halilhodzic maintains his side must be realistic as they attempt to navigate their way out of the group with matches against South Korea and Russia remaining.
“We have a country that loves football, and that trusts this team," Halihodzic said in his pre-match press conference. “I made my players aware of that, but this Korea team is just better than us.
“You have to think each match individually, and consider the opponents we’re facing. We’re not Brazil, who can allow themselves not to think too much on the opposition. We’re not that strong.”
“But we will try to give a present for the Algerian people, they deserve it.”
After allowing Belgium to secure a comeback on Tuesday, the Algeria boss faced criticism over his tactics after going a goal ahead.
“There are so many stupid things being said by the press," he said. "There are a lot of people that could be listening, but I’m the one who chooses the team. I don’t need to talk to the president to tell him how to line up the team. That’s why I’m coach.
“I know what people have been writing about me, and the critics. And I won’t change just because we’ve lost to one of the best teams in this World Cup.
“I have given a lot of thought on my strategy. I had to forget about the Belgium match, and start focusing on Korea. We need to win this one, and also the one against Russia.”
Halilhodzic believes his players have learned from their mistakes in the first match and feels his side will gain support from neutrals on Sunday.
“In football, you have to defend and attack equally, otherwise you won’t win," he continued. “But the team learned this, they are young and, hopefully, things will come out differently this time.
“This team has made a lot of progress in recent years, now it’s up to their passion and discipline.
“I know the Brazilian people love good football, and that’s what we’re always aiming for. So I think we will get their support tomorrow.”
