Halilhodzic said he saw nothing.
"I think it's something that we can discuss in a restaurant, in a bar, now let's talk about a game that was very demanding," he told a post-match news conference.
Halilhodzic said he told his team at halftime not to panic after Russia's strong start to the game. Before Algeria's equalizer, Russia had chances to double its lead. The most notable chance came in the 26th minute when Oleg Shatov weaved through the Algeria midfield but his right-foot shot drifted wide of the Algeria post.
In the second half, midfielder Sofiane Feghouli, man-of-the-match Slimani, and Brahimi all worked hard to help neutralize much of Russia's attack.
"During the first half Russia used its experience, the way they controlled the game, the way they organized themselves, my players were a bit naive but once again this Algeria team has a lot of margin to progress and I suspect that we can go a lot better maybe in the next round against Germany," he said.
History could be on his side. As well as beating West Germany in 1982, Algeria won their previous encounter in 1964.
