If he didn't want to be here he would have handed in a transfer request. Financially that can only affect him positively by getting a bigger wage elsewhere as I doubt he has any contract terms that will cost him money on his current one.
So no actual 'source' then, just your conjecture.
If he's that shit, why do you toffees want to spend anything on him? Why not wait until the end of next season and pick him up for free?
I hope he's practiced the basics all summer - positioning, shot stopping, being a goalkeeper - rather than the passing practice he did previously.
Get those right and he may be a better player than the last time we were in the Championship.
