Former Nigeria international Sani Kaita believes Bosnia, not Argentina, will provide the Super Eagles their stiffest test at the 2014 World Cup finals.
The 28-year-old midfielder posits that Bosnia have great potentials and credentials to prove quite a handful in their Group F pool.
He added that victories over Iran and Bosnia will cement Super Eagles qualification for the knock out stages even before the Argentina game hence the importance of the tie with Bosnia.
"Argentina is a strong force in World football no doubt and games between them and Nigeria have always attracted attention because it will always be tough", Kaita pointed out.
"But I think this time, Super Eagles should be more concerned about the Bosnia game and of course the Iran clash more than the Argentina match.
"Bosnia is strong, they have quality players and the result of the match will determine our qualification from the group.
"If Eagles beat Iran and Bosnia, they would have made it to the next stage irrespective of the outcome of the last group match against Argentina so I believe these are more crucial games than that of the South American."
