Correct. It depends on current form. It also depends on who we are playing, and if experience required, warranted.
For example Manolas transfer market is nowhere near what it was in 2018, when playing at Roma. Still a quality player. On the other hand Mavropanos is valued at 17m euro and is having another solid year at Stuttgart.
