After already signing five new players in the space of a month, new Middlesbrough manager Garry Monk is looking to add a new keeper to the squad.
The man in the frame is West Ham's Darren Randolph, and Boro have reportedly made a £5m offer for the stopper according to Sam Inkersole of Football.London.
The 30-year old Irish international made 22 Premier League appearances for the Hammers last season, conceding 39 goals. Yet, despite making more league appearances, he was still widely seen as the understudy to Spanish keeper Adrián.
With England shot stopper Joe Hart reportedly set to join the club on a season-long loan from Manchester City, West Ham are open to selling either one of their two main keepers.
Randolph in particular has attracted attention, with both Middlesbrough and Premier League new boys Newcastle United said to be interested in the player.
Boro are looking for fresh goalkeeping talent after last year's starter Victor Valdes departed the club following their relegation from the Premier League, to the Championship. Veteran Brad Guzan also left on a free transfer.
New Middlesbrough manager Monk has already signed right-back Cyrus Christie from Derby County, midfielder Jonathan Howson, and former Toulouse attacker Martin Braithwaite this transfer window, along with Bury's George Miller, and Swansea City's Connor Roberts on loan.
