Two ways in looking at that. Either he really wants to come, but doesn't want to get his hopes up too high just in case something crops up, or he is looking for more money and this is the scenario we had with Grabban.
I doubt there will be much difference in wages between any of the clubs mentioned. We are talking about a lad from Cork, not a youngster from Madrids or Barcelona academy. Put it this way I doubt any contract will set him up for life If I were the player it will be down to career progression...
