I don't actually rate Gueye all that highly, but considering how much Silva seemed to want to keep him, and looking at some of the prices that other Premier League clubs are asking for their first team players, I would have expected something in the range of £40-50m. The McCarthy fee was also laughably low (unless the report of £3m was false), even for a crock.
The constant outgoing loans are basically him just kicking the can down the road for another year, but I suppose that it doesn't really matter too much as long as the club is still able to play FFP correctly.
Like I said, I think he's doing a good job overall.
