Visser has a year on his contract and would need to be bought out to go. Can’t see anyone coming in for him.
Or it could be that his contract is cancelled by mutual agreement (possible scenario with The cat also). That would seem the best for all involved. The player(s) get to go where they like and actually play (plus maybe get themselves a longer contract) and the club gets (I imagine) a decent chunk of cap space to spend. Winners all round.
I appreciate there is a few ifs there though
