Sky Sports News claims that Forest have stolen a march on the aforementioned trio and are closing in on the capture of Lewis Grabban.
Nottinghamshire Live recently reported that Forest had “held talks with Grabban’s representatives in the past few days” over a move that could cost £6million.
Forest boss Aitor Karanka has previously revealed his desire to work with the 30-year-old.
“Lewis is a good player and I wanted him when I was at Middlesbrough. In the end he went to Norwich,” he said.
“I can tell you that the striker who arrives will be the right one for this club.
“The striker will be one of the most important signings we make at the club this summer. This player can make the difference that we missed last season.”
Sky Sports report that Birmingham City are interested in Grabban but that a move to the City Ground is now ‘far more likely’.
