Green scored for Oxford in the play-off semi-finals and final
Oxford United have signed Torquay striker Matt Green for an undisclosed fee after a successful loan spell.
The 23-year-old, who also had a spell at the U's in 2007/08, scored 14 goals this season - including the opener in the play-off final win over York.
After signing a two-year deal, he said: "I've been wanting this for a while now. I hadn't felt at home at Torquay, but at Oxford everything feels right."
Green turned down the offer of a new contract from Torquay.
Green joined the U's on loan in November 2007 from Cardiff and had two successful spells that season.
At 23 he's a young lad with bags of potential and we're hopeful that he can continue to develop as a player during his time with us
Oxford United boss Chris Wilder
That summer he looked set for a permanent move to the Kassam Stadium before changing his mind and moving to Torquay.
His re-signing 12 months ago was met by mixed reaction from Oxford fans last summer but several crucial goals, including a late equaliser on his second debut against York and, most notably, strikes in the Blue Square Premier play-off semi-final and final have made him a highly popular figure.
Torquay will be due 25% of any transfer fee Oxford receive for Green in the future.
He is Oxford's fifth signing this summer and follows Asa Hall, Ben Purkiss, Alfie Potter and Steven Kinniburgh to the club.
Boss Chris Wilder told the club website: "We are delighted that Matt has decided to join us on a permanent basis.
"His overall contribution to our success last season was enormous and, alongside Alfie Potter and Steven Kinniburgh, he's another who has decided to return to us after enjoying a successful loan spell.
"At 23 he's a young lad with bags of potential and we're hopeful that he can continue to develop as a player during his time with us."
Wilder's early summer recruiting mirrors last year's policy where nine players came into the Kassam Stadium by 22 June.
Meanwhile, Brackley have signed veteran goalkeeper Billy Turley following his release by the U's.
