I largely agree but it depends on how we go. If we're not scoring goals and losing every week I could see it being earlier. If we start to pick up the odd win/draw here and there then I think he'll see Christmas easily. Worst case scenario and I see a hammering at Bournemouth being a potential turning point when the club start to reconsider their stance (not saying he'd be sacked then but they'd start thinking about contingencies) As I said earlier the Ipswich home game is absolutely massive for him.
To cheer me up no end, Everton have blown a 2 goal lead (with 10 minutes left) against Bournemouth and are now losing 3-2 at Goodison.
