The current SPL leaders arrived Portugal on Monday and are poised for Tuesday’s match at the Estadio da Luz with the assurance that all points would put them on the brink of qualification for the round of 16.
Ambrose said that Celtic was in Portugal to prove a point that they could compete at the highest level and that their victory and spectacular performance over Barcelona was no fluke.
"We arrived in Portugal early on Monday. We are ready for Benfica and our mission is to go all out for the three points at stake to brighten our chances of qualification,” Ambrose told Goal.com.
"We need to show the world that our victory over Barcelona was not accidental hence our resolution to storm Portugal with the ultimate aim of gaining the entire points and putting Scottish football on the world's map for the right reasons," Ambrose expressed.
The Nigeria defensive ace also stressed that he was enjoying life in Glasgow and would continue to relish his good form for club and country.
Celtic are second with seven points from four matches behind Barcelona who are two points ahead. Benfica and Russia's Spartak Moscow occupy the last two positions in Group G.
