Sorry to disappoint, but Nanai will stay a Cowboy. Not sure where CG has received his info but it is well off the mark in this instance.
Leniu and Klemmer still the most likely to join the squad for 2023, along with Bateman. Bateman will depend on transfer fee and personal terms, so there are a few hurdles to overcome there.
Sheens has lined up a meeting with Leniu, Bateman and others while over in England. Unfortunately, i have no info on who the others are.
Talau will be also be apart of the top 30 next season. He has a train and trial contract which will turn into a 1 year contact provided he progresses through the off season injury free.
