High-flying Middlesbrough are understood to be in discussions with Millwall over a loan deal for George Saville, with an option to buy the midfielder, according to a report by Sky Sports News.
It is also believed that the Lions are receptive to allowing the 25-year-old to depart for Tessside, but only in the condition that they are able to draft in a replacement before the August 31st loan deadline.
Boro did previously attempt to sign Saville on the original transfer deadline day earlier this month but saw multiple bids rejected by the South Londoners.
The Northern Ireland international is a former member of the Chelsea youth team and joined Millwall from Wolverhampton Wanderers in June of 2017, after impressing while on loan.
If the move does materialise for Saville, he will be joining a Middlesbrough side on the crest of a wave under manager Tony Pulis, who are currently joint top of the Championship having only dropped two points in their first five league games.
It took a controversial injury-time winner from defender Daniel Ayala against West Bromwich Albion on Friday night, to keep the Teesiders at the summit, but their boss is still looking to strengthen and sees the box-to-box midfielder as an essential addition to his pool of players.
Boro also reached the third round of the Carabao Cup on Tuesday night with a hard-fought 2-1 win over Rochdale United at the Riverside Stadium with goals from Marvin Johnson and Jordan Hugill.
Saville made his debut for Northern Ireland last season and was in the line-up that lost to Switzerland in the World Cup playoffs.
Middlesbrough return to action in a huge clash on Friday night, where they will travel to the team alongside them at the top of the Championship table in Leeds United, at Elland Road, in what promises to be an absolute cracker.
