Algeria captain Medhi Lacen believes his side are ready for the crucial opening match of the 2013 Africa Cup of Nations against neighbours Tunisia.

The two sides will meet at the Royal Bafokeng stadium on Tuesday night in search of maximum points as they look to progress from Group D which includes Ivory Coast and Togo.

''We are looking forward to the start of the competition and the atmosphere within the group is good,” Lacen told reporters at a press conference.

''We are ready; now this is the true beginning of the competition.”

When the two sides last met in a friendly match in 2011 it was Algeria who edged Tunisia 1-0 courtesy of a strike from Ryan Boudebouz, but Lacen says that result is in the past.

“We do not have a psychological edge over Tunisia,” he said. “Since our last meeting their team has changed and it will be a different game.

“I do not think this game will be a decider. If we lose we will be forced to win the next two games.”
