I wouldn't. If there is a club out there that is willing to offer ridiculous money for McKain then surely there will be clubs coming in for the likes of Leo
As noted already, McKain went to Saudi Arabia on the back of the gig his ex-coach got there.
Leo (or any other of our players) have hardly been on the transfer radar prior to the World Cup, and like I've repeatadly said, clubs are extremely reluctant these days to sign players based on three games in the World Cup.
In fact the only All Whites I think may be moving on after this are Smeltzy and Reid, and Elliotttt may get another shortish contract. Think everyone else will be staying put.
It's quite possible some 'lower' overseas teams would be interested in the likes of Leo - whether anything would come of that would depend on $$$. And hopefully Phoenix aren't gonna let anybody go cheaply - which would stifle such moves.
