It appears that we will have to raise funds from player sales in July:

"Documents also revealed that the club’s bank loans have soared to £70million, resulting in an overall debt level of £81million – up from £53million in their 2021-22 accounts.

There will be concerns at Turf Moor that another relegation could plunge the club into financial trouble due to their growing debt levels.

The Clarets are in the process of repaying a £65million loan from MSD Holdings which was taken out during the takeover of the club in 2020 and is scheduled to be repaid by 2027."

Weghorst, Berge, Muric & Wilson are the likeliest departures I reckon.
