According to reports, the English Championship side will make a move for the ADO Den Haag winger during the transfer window.
Boro narrowly missed out on a place in the playoffs, having hoped for a return to the English Premier League.
In an attempt to boost their chances of a return following the 2019-20 season, Boro have lined up a host of potential signings, including Dutch winger Sheraldo Becker.
Becker, 24, is set to leave the Eredivisie club at the expiry of hist contract next month and Boro are said to be keen admirers of the soon-to-be free agent..
The former Ajax Amsterdam youth prospect has scored seven goals and assisted a further 10 in 32 league appearances this season.
While his stats make for good reading, it is Becker's pace and trickery that have reportedly caught the Riverside club's eye.
Den Haag close of their campaign at home to Willem II on Wednesday evening.
