At the start of the summer we were all saying '2 or 3 in', build slowly and don't expect too much from the window.
Naturally, once you've got 2 in, much wants more. We clearly need at least one CB, which I think we will 100% get, having let Williams go.
If we don't do anything else beyond that, I think that's understandable. We're trying to sign players for the long term, not the short term fix, which Richarlison and Digne fit in with. I'd rather us keep our powder dry than panic or splurge on someone who'd only do a job for a season or 18 months, and go back in for better long term targets in the coming transfer windows.
