Bosnia and Herzegovina should have taken a first-half lead against Nigeria when Eden Dzeko evaded his marker and struck a composed finish past goalkeeper Vincent Enyeama.
His tally failed to stand, however, as the linesman raised his flag for offside—denying the Manchester City striker a perfectly good goal.
Then, just a few minutes later, Nigeria's Emmanuel Emenike seemed to grab Emir Spahic from behind before setting up Peter Odemwingie’s goal. Even Emenike hesitated, anticipating a foul, before realising that referee Peter O’Leary had allowed play to continue.
Bosnia and Herzegovina went back down the tunnel at the break understandably aggrieved, and they never recovered.
