And Hopkinson hasn't ruled out making big money sales with the likes of Sandro Tonali and Bruno Guimaraes both targets for major clubs across Europe.
Speaking during the club's financial results presentation, he said: "We haven't got an overall strategy with regards to (moving) players out. We think through what players might or might not want to do this summer.
"But if an (Alexander) Isak-like scenario presents itself again, any player under contract is going to leave on our terms and we're going to maximise the opportunity that might represent for the club. That absolutely does (mean extracting the maximum price).
"For me, Isak was a good sale (in terms of getting a British record fee from Liverpool). I wasn't here for the Isak situation, so I don't want to comment on something I didn't see first-hand. What I do know is that players that leave this club will need to do so on our terms."
