Yes, we have qualified for the African Nations Championship, for the first time ever, and we very much appreciate it.“But there are three very crucial 2014 Fifa World Cup qualifying matches that we must prosecute successfully to qualify for Brazil before we can start the build-up to the African Nations Championship.“Our smart money must be on focusing hard, and without any distraction, at the World Cup ticket," he added.Keshi is expected to harmonise his list and submit a reviewed document to the NFF before the end of the week.
