Forcing players out in Stevenson and Harries case is not really the correct word. The club tell the player they are willing to accept offers and as long as it reaches the valuation of the club the player can leave.
In our situation no matter what the player wants it's very hard for him to step up a level and not get paid more. So 18 told you can leave, triple of wages on a multi year deal then looks really attractive. And almost impossible to turn down.
Now if these lads were on 50 a week at a big club forcing them to drop or leave becomes very hard for the selling club, so although forcing the player out is hard it's not impossible or never not been done.
