Think this rebuild is all but completed now for the time being, especially with Bain looking as being confirmed as the no 2 keeper for the foreseeable now.
When it looks like now that we have great cover in every position in terms of quality available for how Ange wants to set the team up, then the back up keeper remains by far the weakest imo.
Yet it isn't a position you would change unless forced to, so Bain must have plenty about him still to be happy to play that role, and more important Ange must be happy enough with Bain to offer him a new contract also.
So if Ange is happy enough with the situation as back up keeper then I'll be happy enough also, and just continue praying Hart remains available for the foreseeable also.
