Leeds United have seen a bid rejected for the midfielder.
Hamer emerged as a shock target for Leeds United on Monday evening, with The Star reporting on a £13million bid. Sheffield United are thought to have seen that number as derisory and rejected it outright, and it remains to be seen whether Elland Road recruitment chiefs will return with an improved offer before Friday’s deadline.
Having seen Hamer’s relegation release clause expire earlier this summer, there was growing optimism he would stay at Bramall Lane but whether it be Leeds or someone else returning with another bid, Sheffield United look to be putting contingency plans in place. Journalist Alan Nixon reports they have identified Celtic winger Mikey Johnston as a possible successor, should the Dutchman leave.
