Nottingham Forest owner Evangelos Marinakis held a meeting in London last week in a bid to persuade Brennan Johnson to sign a new contract.
Marinakis met with the Wales international's father, David Johnson, the former Reds striker, amidst intense interest in the winger's signature.
Talks were first broached in December 2020 when Brennan was on loan at Lincoln, but his father was concerned about playing opportunities under former manager Chris Hughton and the discussion went no further, Johnson said.
