The Tricky Trees were looking to add both O’Brien and Toffolo to their ranks this summer as they continue their recruitment drive ahead of a first season back in the Premier League.
Nottingham Forest have been in talks with Championship side Huddersfield over a move for the duo and reached an agreement, with the transfer arranged as a double deal.
The Nottinghamshire giants were locked in discussions with Toffolo but have failed to come to terms on a contract, and the deal is now off.
But Forest are still keen on securing O’Brien’s signature from the Terriers, although they have suffered a blow.
Nottingham Forest’s push to land O’Brien from Huddersfield has got complicated as the original transfer was agreed as a double deal worth £10m, before the collapse of Toffolo’s move to the City Ground.
O’Brien has already proved his fitness through a medical at Nottingham Forest and has agreed personal terms over a move, but a deal is not sealed.
Steve Cooper’s side have turned to alternative options having failed to land Toffolo with Real Betis’ Alex Moreno at the top of their wish list while they hope they can still get a deal over the line for O’Brien.
