Ghana’s participation in the 2014 Fifa World Cup qualifiers could pose a security threat, ex-Nigeria captain Sunday Oliseh claims.
Oliseh believes the series of play-off games will decide the continent's five qualifiers may create many problems.
Ghana were handed a tough draw in Group D including Sudan, Zambia and either Lesotho or Burundi in the second qualifying round.
The Black Stars must top the Group before advancing to the third qualifying stage where five different play-offs will take place to determine who reaches Brazil
Since the 1994 finals, Africa's World Cup qualifiers have been decided by the teams who emerged top from selective qualifying groups.
"I think Africa is in trouble as I was very disappointed when I saw the format they made up," Oliseh told BBC Sport.
"Let's not forget what happened when Algeria played Egypt in (2010) qualifying, when there was fighting, yet now we will have five play-offs."
"Let's hope that we don't have five incidents like this."
Security at high-profile African football matches has long been the subject of some concern.
In November 2009, bitter North African rivals Algeria and Egypt were forced to meet in a one-legged play-off after both ended their World Cup qualifying group with identical records.
Such was the intensity of the match in neutral Sudan that diplomatic relations between the two countries were affected as violence broke out between rival fans in four different countries.
"This is what scares me (about the new format)," Oliseh told the BBC's flagship African sports programme Fast Track.
