Nothing has pissed KLP off, he just feels the time is right to move, he feels ready. While that may or not be the case, we can bank an eight figure sum for him which is pretty good going. We might even get him back on loan depending on where he goes.
Acun wants four, not including Slater. Pelkas is one, Iranian lad is another. Should be another striker and a defender coming in to round it out.
Shota will have his own targets too, you might even see somebody from his old club Pakhtakor coming across if the money is right.
I'd be very disappointed if he went now, or agitated for a move now. Give it at least 6 months more, see if we can give him a deal that satisfies him financially, and give him the chance to get to the PL with us next season.
