Let me preface this whole thing with a I am literally completely uninformed label.
If we're bringing in Kelly we won't be paying a big transfer fee because we don't have that money. I would guess there will be some money but maybe a substantial sell on or something. Wouldn't be surprised if he's the highest paid at the club.
From the outside I think Liam Kelly wants to play every week. Bigger picture, the Scotland goalkeeper position is...problematic. Gordon, McLaughlin & Marshall aren't getting any younger and there isn't anyone seems a stick on to take over. We know from SOD that playing for Motherwell isn't going to hold him back while Clarke is in charge. I don't think he's a million miles away from a call up if he's playing every week.
