Alot is at stake for the Zimbabwean - their government has put a bounty pool on the game against Nigeria; I'm hearing $10k per player if they manages to beat Nigeria in Akwa Ibom this week. That's enough motivation for them.
We haven't won against Zimbabwe since 2019 hope we can change that this week and maybe move to the 2nd place if Benin Republic loses to South Africa.
Money is a strong motivator. However I don't think zimbabwe will be able to upset the super eagles of Nigeria, given Nigeria's squad depth and overall quality. Although the super eagles haven't defeated Zimbabwe in recent times, playing in Akwa Ibom gives them a strong home advantage, which makes an upset even more unlikely.
