Strange one all of this. I'm surprised we didn't identify a number 1 keeper early and just go for it. All this wait and see with Hart doesn't seem to benefit us. If he comes on loan you know he could be off at any point. Would rather continue with Stek and give him a chance and if he proves not to be up to it we can target a keeper for January who actually wants to come to us.
think the idea seemingly was to get a decent solid keeper that Koeman trusted in early on the cheap (Stek) to patch up the issue of only having Robles.
That doesn't mean we wouldn't be going for another keeper, but at least allows us some breathing space. The best deals often pop up towards the end of the window (not particularly in regards to value, but with players becoming available).
This year that will only be more prevalent due to the fact that the Euros were on, and so many teams (and big ones at that) have new managers who needed/wanted to fully assess their squads through pre-season first.
