His leaving must have come about after not being assured of being No 1 here as he has allegedly taken a pay cut and ruined any chance of replacing Heaton in the England squad and not gained a lot by moving home nearer to Leeds, So a generally strange move.
AA Route planner says 2hrs 5 mins via M1 Leeds to Brum so I would suggest that he has moved to around The Peak District thus cutting the journey time in half to either.
Probably too far to live and travel every day. If that had been the criteria would his agent have not approached Huddesfield or Wednesday so they could cash in on Westwood or even Middlesbro or Hull who were seeking a keeper.
