If i was Butland id see Jags, Baines and Stones as fellow England players in the defence and think that may play a part in England selection..then see Barkley and Cleverley as other infernationals for more exposure.
For Stoke, the england manager is solely going there to watch him.
This is one of the biggest managerial decisions for Martinez. Does he stick with Joel and go for a young keeper to possibly dislodge him OR an experienced backup...
Or does he go to the board, tell them he wants to have the £50mil tv additional revenue for transfer fees and move on a heap of deadwood for wages....
Then launch a bid £20-30mil for Butland....this is what i would do as with Butland or someone of that quality it could mean champions league and at the very least 10 years of extra placing money....
Key would be Butland pushing for the move.
