I think the priorities arein no particular order)
GK
Midfield
Striker
Positionally, it will depend (as is usually the case) on availability/money/need & blending into the side.
Barring departures which would obviously change things I would proiritise (in a particular order)
Central midfiled 1 or even 2 players
Central defender
keeper
Left midfield
If Berba were to go then obviously a striker would go to the top of the list.
But any which way I look at it I can't see the right sided positions being anywhere near priority and therefore can't believe that young Aaron will be going anywhere any time soon.
