Whatever Waine decides I'm sure it will be done in consultation with the likes of Bazeley and Wood (as mentor).
But he unlike say Mata has English heritage, and he'd clearly stated it was his dream to play in the UK. For sure he'd love to go to a WC, but I think the main driver will be what's best for his overall future career. Touch wood any AWs back up strikers at the WC next year will be getting splinters whilst our EPL hero does his thing for 3 games. Waine at 23 will still have 2030 & 2034 to look forward to.
As I put in another thread (Nix v Victory game) there are plenty of examples in the UK of guys who at his early 20s age were down in the 5th/6th tiers, and who then have gone on to crack it at League One/Championship level. He only has to look at Lee Gregory and Will Evans in the Mansfield T changing rooms.
Could be totally wrong, but just sense a return to the Nix might feel a bit meh to him, as in been there done that. Imagine it will come down to what UK clubs, if any show an interest over the English summer. Plus yeah his state of mind, if the long winters and lack of playing time have just got to him mentally.
Mata's parent club Shrewsbury Town (2nd last in L1) have been having trouble score goals for at least 2 seasons. If they are relegated to L2, you'd think they would be one of the stronger clubs in the 4th tier next season. Just one possible destination?? Maybe old coach Des Bucks will pop up somewhere in League One, and hatch a plan to get the best out of Ben??
Edit - oops ignore that. Swansea City rumoured to be looking at Buckingham as a new gaffer!
But Des likely another sounding board that Waineo consults with in the UK.
