BalebaThat's how I saw it. Admittedly it's a friendly and there's going to be a few experiments but it was noticeable that Hurzeler seems prepared to try players in new positions. Baleba was definitely playing CB as was Weir (think he's normally a midfielder?), and Moran, Buonanotte and Ayari looked to be playing CM. I think there were a few occasions when Moran, who looked good to me, was upfield beyond the striker, but he was often quite deep collecting short passes from the CBs. I might be wrong but perhaps he could become the replacement for Gilmour if he leaves? Personally I hope he doesn't persist with Baleba at CB - seems a waste of his talent/best skills but like you I'm far from an expert and if that's what the management think then I suppose they know best.
Just to add to what others have said - we've got loads of 18-22 year olds coming through. If just 10-20% are good enough for the premier league then Tony's long-term plan is going to start reaping even more benefits. And Barco is going to be a superb player for us (although I can't see him staying that long).
