Stranded Although, didn't Suraez have a release clause of £20m or so in his Liverpool contract as Arsenal offered a quid more. They were told to f-off and they eventually sold him for much more to Barca, so even a release clause may mean very little.
I think he then signed a new contract getting rid of the release clause
of course nothing stopping Olise doing that - another club could offer the £8m and then Olise sign a new contract with us superseding the old one. Which I think sounds like what we are trying to get him to do now. Very much doubt he will though
