Michael Mancienne is set to have a medical ahead of a move to the City Ground.
Once tipped as a future England star, Mancienne has featured at every youth level for the national team. He left Stamford Bridge for the Bundesliga in 2011, and his performances in Germany made him a top target for the Reds this summer.
The 26-year-old was a key player for England's under-21s during Pearce's stint as manager, and he will be hoping that a return to the Premier League could revive his career.
Mancienne will bring great versatility to the City Ground. He can play in the centre of defence, at full-back, or as a holding midfielder.
He is expected to undergo a medical today after personal terms are agreed upon.
Forest have already signed defenders Louis Laing and Roger Riera on free transfers this summer, as well as forwards Matty Fryatt and and Lars Veldwijk.
