Benitez defends zonal marking

The Reds conceded their third goal in three games from a set piece to lose their Champions League game at Olympiakos, but Benitez is determined to stick with zonal marking.

"The problem is not the system, the problem is perhaps their mentality," he said.

"We have to change our mentality to have more confidence in ourselves and to understand that the away games are more difficult because then we do not have all of our supporters behind us."
