Norwich have signed Newcastle midfielder Matthew Pattison permanently for an undisclosed fee and brought in Chelsea defender Ryan Bertrand on loan.
Pattison, 21, has signed for three and a half years after a successful loan.
Bertrand, 18, was recently on loan at League One Oldham and will stay with Norwich until the end of the season.
Boss Glenn Roeder told his club's website: "We have been following Ryan and been very impressed. We believe he can step up to the Championship."
