Derby paid £750,000 for Dickinson in 2008
Plymouth Argyle are set to make former Barnsley striker Liam Dickinson their
third new signing
of the close season.
The 25-year-old was released from his contract at Oakwell last month having struggled to make an impression, making only four appearances last term.
As a result, Dickinson was sent on loan to both Walsall and Rochdale over the course of last season.
Argyle boss Peter Reid said: "He needs to get his career back on track, I think it's a great opportunity for us."
He added: "I can only help the boy, he's got to do it himself and it seems to me that he's got the bit between his teeth ready to do a job for us so I'm delighted he's agreed to sign."
Dickinson began his career in non-league football before a successful trial with Stockport County led to a first professional contract. His 21 goals in 2007-8 played a huge part in Stockport's promotion from League Two.
In 2008 Derby paid £750,000 for Dickinson, but he failed to make an appearance for the club, and subsequently had loan spells at Huddersfield, Brighton, Blackpool, Peterborough and Leeds before moving full-time to Brighton.
