Brentford striker Marcus Forss is finalising personal terms with Middlesbrough ahead of a move up north.
The Finland star is set for a permanent transfer to the Championship club.
Forss, 23, made seven appearances for the Bees in the Premier League last season without scoring.
However, he finished the campaign with six goals in 12 games for Thomas Frank's men after netting five goals in four games in the League Cup, including four in one game against Oldham.
On transfer deadline day in January, he moved to second-tier Hull City on loan, scoring once in 11 appearances.
