Alternatively, I think even if we'd have bought 2 CB instead of Digne and Richarlison we wouldn't have been much better off. Probably preferable to get defensive players in first as they arguably need more time to gel, but we probably acted on the 2 purchases as the opportunity presented itself.
The question we don't really know the answer to is were they looking for CB's from the moment they arrived? As everyone here knew it was a key weakness. If yes, I don't have a problem. If no, then we will undoubtedly have problems in the early stages of the season because of their priorities.
