Newcastle United manager Eddie Howe says the way spending rules in football are working at the moment is "not right".
The Magpies were forced to sell players in the summer to balance the books under Profit and Sustainability Rules (PSR).
Elliot Anderson and Yankuba Minteh both left Tyneside for fees in excess of £30m, to Nottingham Forest and Brighton, respectively.
And Howe, speaking on former Crystal Palace chairman Simon Jordan's podcast Up Front, admitted: "I felt really uncomfortable in the summer when we were forced to make sales of two really talented young players in Elliot Anderson and Yankuba Minteh, against our will really for financial reasons.
