As Bruno proved when we signed Rosenior - not impossible that existing keepers (if both sign) up their game accordingly.
Bruno has been on one year contracts for last three or four years - every year he had just got better and made a new contract inevitable
Much the same with Sidwell really -...
a few bad results may knock keeper confidence next season - plus far more likely to rotate and drop keepers next season
this is why we want three senior keepers
