Even given our context as not being a top4 club IMO this transfer window is shaping up to be bloody brilliant.
The UEFA window hasn't opened as yet and it looks like we have all but confirmed at least 4 senior players, of whom 3 can be expected to be looked upon as starters. Further to this we are reportedly still in talks with at least 1 more CB of starting level, and possibly a wide player and another CM/AM, and all this before we know who is staying and who will be sold.
IIRC there was early talk that we / Mislintat wanted to sign a new back 5 & it was generally dismissed as being crazy - doesn't look so far fetched now & we could well end up with nearly half a new team or more depending on departures.
