I was thinking his value would be around the 6m mark, especially when keepers don't tend to go for loads (with the exception of a few)

Let's be real, he was in league 1 before we picked him up and has had one really good season in the top flight, 10m is a lot for him. I would hate to see him go, but with a good championship keeper like Smithies on the bench as well as 10m potentially being reinvested into the midfield or a striker, I'd take it all day
