Nigeria played out a goalless draw with Iran at the Arena da Baixada in Curitiba, an encounter Kuffour described as the most disappointing match at the on-going 2014 Fifa World Cup in Brazil while lamenting the poor tactical organisation of the team.
"They (Iran) came with a game plan and its suit them, because they were just there and waiting for their chance - could be at set-piece or counter attack, but Nigeria didn’t come to the fight," Kuffour said on SuperSport.
"You can see how many balls Nigeria did lose in the midfield? They really wanted to kick the ball from the beginning with one player up front with Emenike and had limited chances on two-on-one occasions upfront. They (Nigeria) only had an advantage when Shola Ameobi came on with his height but still not good enough.
“I'm really worried how Nigeria will cope playing against Bosnia-Herzegovina and Argentina," the former Bayern Munich and Roma defender continued.
"This game has been worst game in the whole tournament - we didnt see any quality in this game. Nigeria didn’t prove anything. If Nigeria want to qualify for the next round, this is the game that should be the must win game for Super Eagles.
"And Nigeria didn’t win, so I doubt how they will cope with Bosnia-Herzegovina and Argentina. I’ve always said winning your first game is crucial to reaching the knockout stages. Since, Nigeria failed to win, I’m in doubt how they will progress," Kuffour concluded.
The Super Eagles will next face Bosnia-Herzegovina in their second World Cup group encounter on Saturday before taking on Argentina five days later.
