We have competition in every position, which can't be bad.
I'd leave Grant out completely as I think our best midfield is Bridcutt, Jones and McGrandles. Harsh on Grant, but Elbouzedi has missed out so far after an excellent pre-season. Melbourne has done nothing wrong, but Roughan is a better bet and will probably start on Saturday. Ross did nothing wrong in pre-season, but has rightly lost out to Palmer. Morton had a decent game last night, but Hooper will most likely start at MKDons.
When Archibald, Lewis and Walsh are fit and the new forward comes in, the hard job will be keeping them all happy with enough game time.
For all my criticism about MA's style and performances last season, and his speed in getting rid of the old squad in the summer, his recruitment has been top class. Everyone I have seen is comfortable on the ball and work really hard. Early days of course, but so so promising. We do need to get better at defending set piece crosses though!
