Norwich will sign Bradley Johnson, subject to the relevant paperwork being completed, after the midfielder's contract with Leeds expired.
The 24-year-old is to become Paul Lambert's fifth new addition of the summer, following strikers James Vaughan and Steve Morison, winger Elliott Bennett from Brighton and young Belgian defender Richie De Laet on loan from Manchester United to Carrow Road as the Norfolk club prepare for a first Barclays Premier League campaign since 2005.
Johnson, 24, told the club's official website, www.canaries.co.uk: "I am over the moon really to get the chance to play in the Premier League with a big club like Norwich City and under a great manager who I have a lot of respect for."
He added: "He is done a fantastic job since he arrived at Norwich and that was one of the main factors in me signing with the club."
Johnson, born in Hackney, started his career in East Anglia as a trainee at Cambridge, before joining Northampton in 2005, and transferred to Elland Road three seasons later.
The combative midfielder made more than 100 appearances for Leeds, scoring 17 goals including a long-range strike in last season's FA Cup replay against Arsenal.
After Leeds missed out on promotion, finishing seventh in the npower Championship, Johnson is relishing his first taste of top-flight action with the Canaries.
Norwich are also said to be closing in on Anthony Pilkington after Huddersfield revealed the 23-year-old winger had asked to leave.
