Below is what Arsenal is saying, but I believe it has to do with Nigeria being unstable with security issues here and there, guess they probably dont want to just come out and say "We are not coming to your Country because of Boko haram"
Arsenal
marketing director Angus Kinnear said: “Bringing a top-level club to an
international market is always complicated and logistically challenging. With
the proposed match in Nigeria planned for early August, we could not get
comfortable on everything needed to satisfy our requirements, so we have
reluctantly taken the decision to postpone the team’s visit.”
Kinnear continued: “We have
a huge and loyal following in Africa, and we are sorry that the team will not be
visiting this summer. However, we have a long-term commitment to Nigeria and we
are already making plans for a visit next summer.
“In
addition, we also have some exciting forthcoming activities planned with our
commercial partners in Nigeria – Emirates, Airtel and Malta Guinness, which will
kick off in the next few weeks
