Celico, little known in his native Argentina, could help to dash the hopes of Lionel Messi's team if his Ecuador side denies the South American giant the win it needs in the final qualifier on Tuesday in the tricky venue of Quito at high altitude in the Andes, Reuters reported.
"Destiny put things in your path that you don't imagine," Celico was quoted as saying by Argentine broadcaster TyC Sports.
"I have a big commitment to the people of Ecuador, because I have done my (coaching career) here. Today I have to be thankful for that and do my best, as is right," he said when asked what it meant to face his country.
Argentina's current campaign, in stark contrast to the last World Cup cycle when La Albiceleste qualified comfortably and reached the final in Brazil, has been dogged by Argentine FA mismanagement, two changes of coach and poor results.
Gerardo Martino steered Argentina to the Copa America final in 2015 but the side lost on penalties to the Chile team managed by Argentine Jorge Sampaoli, who is now at Argentina's helm.
Chile was under Argentine-born former Spain striker Juan Antonio Pizzi when it stunned Argentina again a year later in the final of the Centenary Copa America in the United States, also on penalties after another 0-0 draw.
That result promoted Messi to quit international football, fearing he might be responsible for his country's jinx.
Martino also quit but Messi came back under new coach Edgardo Bauza, although the team did not improve and he was replaced by Sampaoli.
Meanwhile, Peru was beginning to rediscover the sort of form that saw it reach three World Cups between 1970 and 1982, its last, under Argentine coach Ricardo Gareca.
Peru held Argentina to a 0-0 draw in Buenos Aires on Thursday that left Sampaoli's team in sixth place in the 10-nation South American group, out of the qualifying places for Russia.
The top four qualify automatically and the fifth-placed side go into an intercontinental playoff against Oceania winner New Zealand.
A bad omen is that Argentina began its qualifying campaign with a shock 2-0 home loss to Ecuador two years ago when Los Amarillos were coached by Argentine Gustavo Quinteros.
