Samuel Eto'o is adamant that Cameroon will reach the quarter-finals of the African Cup of Nations.
The Inter Milan striker helped to keep the Indomitable Lions on course for the last eight on Sunday as he found the target in a 3-2 victory over Zambia.
Having slipped to a shock 1-0 defeat to Gabon in their opening game of the tournament, it was imperative that Cameroon took maximum points from that fixture.
They are now well-placed to book a safe passage out of Group D, with only a point needed from Thursday's meeting with Tunisia to see them through.
Eto'o is confident they will get the required result and is hoping Paul Le Guen's side can claim continental glory for the first time in eight years.
"I am sure that we will give 100 per cent and get enough points to qualify for the quarter-finals," Eto'o said.
"We were unlucky against Gabon, but we were not good enough to equalise after conceding very early on.
"But we are Cameroon, we have won the African Cup of Nations four times, and we are a big country in the football world.
"We have to start showing how good we are."
