Not sure I would describe it as a 'fire sale', we are selling some players and buying others.
From what I hear we are trying to sign a winger and a striker, so it makes sense to sell at the same time (from what I hear incoming will cost more than the outgoing).
We have sold Lascelles (and loaned him back) and signed Mancienne, Laing and Rierra, not sure that weakened the defence.
We will need to replace our keeper in the next year.
£7m for Darlow and Lascelles is on the low side but ultimately doesn't impact the football team this season.
