Everton boss Roberto Martinez defended Blues fans after disruptions during the Hillsborough silence prior to victory over Sunderland.
Martinez blamed a misunderstanding for a minor disruption to the minute's silence in memory of the Hillsborough victims before the game.
He said: "There were a couple of shouts, but I think it was people entering the ground and I don't think they were aware we were marking the minute of silence.
"We all know that football fans everywhere in the world have incredible respect for what happened 25 years ago, and today the silence in the ground was full of respect.
"It was a clear incident of a group of people walking in and I don't think they were aware what they were disturbing at that time."
