"We've been working on this for a little while now, since we got promotion," Brian McDermott said. "It was really important to me that we got a player of Garath's quality through the door.
"Nick Hammond has been speaking to Nottingham Forest and Steve Cotterill and Garath has arrived here on a Bosman - we're absolutely delighted to get him.
"He was at Slough, an old club of mine, about seven or eight years ago. And I've known about him for a long time now.
"And he's coming of age. He scored four goals in one game in the Championship last season and he's got a real eye for a goal. He's got real pace and an energy about him.
"He's quick, he can cross it, he's got a trick, and he can score goals. He's young, he wants to work hard and improve. In all the players that we've got here, that's a key attribute. They've all got ambition, but they all want to work hard and get better.
"They are all 'team' men - and that ethos won't change, no matter what league we compete in. He's a really nice lad too and he'll fit into what we're doing here. Our ethos will stay the same."
"There has been a hell of a lot of interest in Garath - from the Premier League, the Championship, and Forest wanted to keep him. Luckily, he's decided to come here and we're fortunate that we've managed to get him.
"It's an early signing for us, and a great one! We're very, very pleased."
