Despite winning promotion to the Premier League last month, Burnley may be forced to sell Chris Eagles and Chris McCann this summer.
The Clarets' operational director, Brendan Flood, admits that the duo, who were linked with moves away from Turf Moor in January, may not be with the club when the new season starts in just over two months' time.
He told the Lancashire Evening Telegraph: "We've got to be careful not to make mistakes. I think you can get caught up in the noise of the Premier League and end up spending loads of money.
"In an interview, (Stoke City chairman) Peter Coates said he felt they'd made a number of mistakes last season, like signing (Dave) Kitson from Reading for £5million.
"Inevitably, if we were in the top half of the Premier League we'll get bids for players, and you've got to be open-minded and say, 'We might sell someone for £5million plus, because that's good business'.
"Then you can buy another lad who's as good as Chris McCann or Eagles for £1million from lower down. We've got to be prepared to do that."
