Your success this year will be your biggest downfall.
Ashley will cash in on Tiote, Krul, Ba etc in the summer
Firstly, cashing in again suggests he will take the money and run, again I'll point out the hundreds of millions spent and not taken a single penny out of the club. The Carroll money was reinvested WISELY in players and their wages, at the right time and have gotten exceptionally good value out of it.
If Ashley does sell players it will be because the deal is very favourable, gets more cash than the player is worth, buys in an equally good player(or better) on a better deal, whole club profits from it.
Their biggest success this year has been hugely down to selling overvalued players, and buying in undervalued players. If he does that again, it means an even stronger team. They still lack strength in depth, though Perch and Williamson looked pretty damn good the majority of the game.
Doesn't look to me like Ba wants to move on instantly and Cisses won't move on after 6 months. The fact is, that if Newcastle get European football at this point I'm not sure why any of the players would want to leave.
The way Newcastle screwed up before was, getting into the CL spending money they didn't have and keeping players they could have made killing on. Cashing in is the BEST WAY to run a football club, not the worst, and its the opposite of what so many teams have done in the past decade when they hold on to players too long, lose money, invest money they don't have and end up in terrible trouble.
Their success this year, will breed more success if they continue to sell and buy as incredibly well as they have for now basically 3 years on the trot.
