With the January transfer window now open, we look at some of the deals which Nottingham Forest have previously completed that they may wish they hadn't...
Dobie cost Forest over £500,000 back in 2005 when they signed him from Milwall, but he goes down as one of the worst players to wear the shirt in recent memory.
The striker suffered a range of injuries while representing the Reds, but even when fit he was well off the required standard.
Three goals in 41 games does not make pretty reading and it is hardly surprising that his career has petered out since leaving the City Ground.
Powell joined Forest at the back end of his career, but he rarely showed the quality which had made him a Premier League player previously.
Deployed in central midfield for Forest, having returned to English football from a spell in America, Powell was expected to give the side an experienced head to build around.
However, the Jamaican had lost all his mobility by the time he arrived at the City Ground and never looked good enough. It was unsurprising that he retired just a year after joining the Reds.
King cost Forest nearly £1 million, but rarely looked bothered about living up to this fee.
The forward frustrated fans with his lethargic performances and his questionable attitude, and his talent never showed.
King had been a regular scorer for Gillingham, but he only notched 10 times in 50 games during his five-year stay at the City Ground and he goes down as a terrible purchase.
The powerful front man played just six times for Forest before it was evident that he was nowhere near good enough for the club.
Dadi didn't manage to hit the back of the net during his time with the Reds and his clubs after departing probably suggest his actual level.
Dadi moved to Hapoel Acre after leaving the Midlands side, before representing the likes of Wellington Phoenix and Manado United prior to retiring.
Silenzi signed for Nottingham Forest as Stan Collymore's replacement, but he wasn't fit to lace the legendary striker's boots.
The Italian joined for a eye-watering £1.75 million back in 1995 and was handed a contract worth £30,000 a week, but he did nothing to justify the fee.
Silenzi lasted just a couple of seasons at Forest, with his two goals coming in cup matches against lower league opponents Oxford United and Bradford City.
