Our biggest problem this summer is going to be the unending threat that McGrath could go. Potential buyers possibly holding on to see if we'll weaken and let him go for less, all the while we can't replace him on the off-chance he stays.
The uncertainty will be horrendous to live with, but I don't think there's any getting around it, short of him signing an extension.
There's a good chance of an RoI call-up for their summer training camp, too, which will raise his profile further still. If he is to move on, then a big, early bidding war would definitely be best all round.
