So because he has a clause in his contract, he might look to use it. What a total non story.
The bigger question is when does that clause become invalid, im assuming he cant turn round in 2020 and say you changed coach 2 years ago i want to invoke my clause now.
I would also question why he would want to go to bath and potentially be behind both Preistland and Burns in the pecking order.
As for Sale i think that would be a silly move, settled down south, with family around him or move to Sale and have nobody.
