I expect one first teamer, a quality right back.
I would like a second first teamer at right mid but would settle for a young upcoming right mid who we could bring on.
I would like a quality centre forward but do not expect one.
I would be unhappy if we didn't get a quality right back in with no explanations as to why we are finding this so difficult.
To bring in no one would be a failure of the manager in the transfer window, in my opinion. This to me would signal the need for the manager to hand the actual getting of players over to a third party after he identifies his targets.
Having said that I admit to being completely unqualified to make the above statements, this is just my layman view.
