Aston Villa midfielder Jack Grealish could be on his way back to the Premier League.
Boro are interested in signing Grealish should Gaston Ramirez leave for Leicester, says the Daily Mail.
Aitor Karanka has missed out on Robert Snodgrass, who is joining West Ham, therefore still wants to add a midfielder to his squad as Boro try to avoid relegation.
Grealish has battled for consistency at Villa this season, but remains highly regarded.
