West Ham United manager Slaven Bilic is reportedly looking to bring in goalkeeping reinforcements in January, prompting speculation over Adrian's status as first choice at the London Stadium.
The Hammers have the second leakiest defence in the Premier League, having conceded 23 times in their 12 games to date, and sit just one point above the dropzone.
According to the Daily Mail, Bilic is looking to act in the mid-season window by bringing in a new face "of the calibre to replace Adrian in goal".
The newspaper suggests that Manchester City's Joe Hart - currently on loan to Torino in the Serie A - as well as Liverpool's Simon Mignolet and Chelsea's Asmir Begovic are all under consideration by Bilic.
Adrian has been a virtual ever-present for West Ham since his arrival from Real Betis in 2013, having made 101 league appearances to date.
