The Irishman has started matches against Leicester Tigers, Harlequins and Oyonnax as he enjoys a new lease of life under Director of Rugby Dean Ryan.
And he admits he has relished the new set-up at Sixways. He added: "The intensity of training has increased this season. There's a completely different structure and a better environment.
"It takes time for new players and coaches to click but we're all confident we'll come into our own soon.
"I'm enjoying it. There's a good culture being created here. It's been thoroughly enjoyable but it's been disappointing with the results.
"Personally I'm just going to put my best foot forward and it's up to the coaches if I'm picked. I want to play and I want to help this side be successful."
