I think we're certainly not going to be short of firepower at the top and watching the movement of the team in pre-season, while great, is generally a zero indicator for how well we'll do during the season. My only concern is that if you push these players like they were last season, and injuries start to creep in you're going to be back to square one with no sub options to keep players fresh as the season progresses.
But this is a new manager with a new philosophy on how to do things, so I'll give him till Christmas to see what he has in store for this team. Won't lie, I like what I am seeing so far.
