Maybe but he won't be will he.
I assume you meant he won't leave Sarries, I'm inclined to agree. But, rumour has it they offered both Vunipolas less than what they're currently on, hence they're tempted by Top14. Unless they pay Loz a lot more than what he's on, I could see him leaving.
But joining us? Yeah I doubt it unless we somehow offer him a big bag of cash, but we don't seem that way for backs in this country.
