No idea why Hutchinson isn't starting, but from what I saw, he should be. Akinola has improved quite a lot. He looked a bit lost when he first joined. But I put that down to the coaching on both fronts.
He was injured and the team was in good form. Guessing the coach not trying to ruin the flow. He will be starting soon enough. Him and Taylor-Hart coming off the bench is a dangerous combo for tired defenders to have to deal with.
