I reckon we're likely to play with 3 upfront or 1 upront with 2 wingers, however you want to look at it. The 442/424 with Lallana and Chamberlain on the wings would leave our fullbacks exposed and our midfield dominated (long balls up to Lambert).

That's with the team as it is. Looking at those, the front 3 is a good as we're going to get, so I could only see backup players coming in here. At more than £3m, Maynard wouldn't be one of them. Maynard himself came from Crewe when they weren't in the Championship, so we may be able to sign another young player from L1 or L2 with potential to improve.
From those 2 teams, it seems like the midfield and defence are the priorities.
