If it is a discussion forum, why are you making claims about arguments being immaterial? My view is it's the decision for RdZ and, potentially, the (goalkeeping) coaching team.
Fundamentally disagree with this. We've got very little evidence of Steele on crosses. We've got an abundance of evidence on Sanchez. He's made one glaring error since he came in, what, three years ago. He's also got some of the best stats on commanding the box aerially of all keepers in the PL.
