The question is whether his fitness can actually improve, or whether what we see, is what he is. It was his weakness as centre mid last season & currently, he is absolutely nowhere near fit enough to play as a Gurdiola left back. He isn't actually fit enough to play centre mid either, for 90 mins. I was expecting a big improvement in that regard, after training with City rather than PSV. Can't see any improvement at all on that showing. No question re ability imo, it's all down to fitness.
