There's no logic in giving him the rest of the season, then binning him. You either get rid now, and hope for some sort of reaction (and some points) in the next 5 matches. That's not much of a risk, because we don't look like getting any more points as things stand.
Or you give him a 2nd season and hope he'll rediscover winning ways.
