The one notable thing about the current hierarchical set-up is that information doesn't tend to leak into the public domain from our end unless it's of our own volition, and so when we do hear about a transfer, it'll (hopefully) be when it's pretty much concluded. This gives me hope that the wheels are being greased for a good few additions towards the back end of the week.
Should we manage to get Kean (35m and Gbamin (~28m) over the line (which do look for all intents and purposes to be go'ers at this point), we'll be left with a shortage of options at RB, CB and LW/RW. Granted, Delph & Gbamin together could provide adequate cover across the back-line if need be, but it would be far more preferable to acquire a long-term, permanent fix at CB or RB during this window (~20m fee, high ceiling, manageable wages, big ambition).
IMO, Zaha wouldn't provide good value for money considering the outlay (75m+), Malcom looks to have suitors (Zenit,Dortmund) willing to meet Barca's valuation, and it looks like an astronomical fee would be needed to prise Neres from Ajax this summer (€50m for big talent ultimately unproven in physical league). As for alternatives, I'm unsure as to why Ziyech has never appeared as a viable fit for our model given his €30m release clause and left-footed dexterity (alternatively, that Lookman from Leipzig looks a talent).
