Middlesbrough have accepted a bid of around £13m bid from Atalanta for midfielder Marten De Roon.
The Dutch player is set for a medical in Italy today.
The 26-year-old joined Middlesbrough for £12m from the Italian side but now is on the verge of returning to Atalanta.
Middlesbrough boss Garry Monk has also confirmed Marten De Roon is talking to another club, who were understand to be Atalanta.
“Nothing is 100% at this moment in time,” said Monk today. “We’ve allowed him to speak to another club and there are still some things we need to do in terms of incomings and outgoings.”
Atalanta are keen to sign de Roon and ensure he is bedded in well in advance of their new league campaign, scheduled to get under way on August 20.
De Roon joined Boro last summer and made 35 appearances in 2016/17, scoring five goals, but struggled for consistency during his Premier League baptism of fire.
But the former Heerenveen star did end the campaign strongly, scoring the winner against Sunderland in April, and previously scored a memorable last-gasp equaliser at Manchester City
Middlesbrough have spent heavily during the summer transfer window with £15m striker Britt Assombalonga heading a big list of new players.
The others include Darren Randolph, Ashley Fletcher, Martin Braithwaite, Cyrus Christie and Jonny Howson.
