It's a tricky one to answer, as you say - none of us really know a great deal about the new guy, so it's hard to get excited or depressed about him either way. I think he'll need to hit the ground running for his sake, a win against Everton would be the perfect start and from that point on I think we could all grow in confidence that the team is still together, and will still continue to improve.
That's what I hope will happen, but it's all very up in the air at the moment. Either way though, we're either going to have a storming 2nd half or we'll be relegated. I don't think there will be any middle ground with this one.
