I doubt the plan is to sell Murphy or Skalak - the club made a point of featuring Skalak in the PL photoshoots, which they certainly wouldn't have if he was half way out of the door.
However, "Every player has a price" of course.
I'm not actually sure we'll bring in a winger now anyway - maybe...
GK 2 : Maenpaa ( free agent, agreed deal, not announced )
GK 3 : ??? ( May end up being Sanchez )
Left Back : Suttner, impasse over fee.
Utility defender : Gomez, waiting on Liverpool.
Central Mid : Delaney, impasse over fee.
RWing : Cafu ? Coco ? Haraguchi ?
Striker 1 : ???
Striker 2 ...
GK 2 : Maenpaa ( free agent ), no idea reason for hold up.
GK 3 : ???
Left Back : Suttner, impasse over fee.
Centre Back : Gomez, waiting on Liverpool.
Central Mid : Delaney, impasse over fee.
RWing : ???
Striker 1 : ???
Striker 2 : ???
How many in before the squad fly to Austria for training in 20 days time ?
Surely 1 of the strikers and the leftback will be signed by then. And Maenpaa will have found his pen.
