23 goals for in 22 games is very poor when 9 of those games were against Oceania opposition, and you have a (now) EPL striker in the team.
Only scored more than 2 goals in a game twice under him too. And it's not just the OFC oppositions, there have been games against AFC teams (Thailand, Myanmar, Oman) where you'd have thought we'd have a decent chance of scoring some goals.
