From my source
The money is available and has been all window, the board is supplying a top 4 budget this season.
The problems seem to be that Karl didn't know what system he wanted to play at the start of the window, he also outlined players but had no back up players for when his first targets went elsewhere. He spent around 10 days in Spain right when the transfer window opened and players returned to training, his lack of being able to board a plane and lack of a DOF doing deals over here cost us. We were relying on loanees from premier league sides who have gone down the route of sending that player elsewhere.
