You’re moving the goalposts now, you said we’d get relegated if all we did was add 3 or 4 to what we have. At best that’s hyperbole!
Of course if a number of our better players leave a hell of a lot will rest on how we replace them, as is the case for every club in the land.
I stand by the fact we will struggle if we only sign 3-4 players and no one leaves. That would give us a bare decent 10-11.
That said given where we are it us inevitable there will be departures, some we will be pleased to see (Kasim, Bowditch etc) Some will be not what we want to here (moat likely O Donnell, Facey etc). Time will tell and as you say how we replace them is key.
