Sels is good, he hasn't seen enough of Miguel to say. I think Davies has changed the headline as I thought an earlier version implied Belshaw was going to give an opinion on who the better of the two but it's not that.
Basically analyses a few goals and saves, primarily from Sels, and talks about technique and explains why they've taken certain decisions and what their thinking will have been in various scenarios and goes through some general stuff about goalkeeping training etc. Belshaw talks well and gives an interesting perspective.
