Bundesliga side Mainz are now leading the race to sign a Premier League midfielder who has been linked with West Ham and Newcastle United, according to talkSPORT.
The Hammers have appointed Graham Potter as their new manager and are keen to back him in the transfer market this month.
At Newcastle, Eddie Howe is also in the market for reinforcements and could have extra wiggle room given Isaac Hayden’s exit, while Miguel Almiron could also yet go.
