Roger Johnson is set to complete a move to midlands rivals Wolves. Wolves have reportedly had a bid in the region of £7million accepted by Blues for the 28-year-old centre-back. Johnson said: "We're half-way there. "It wasn't an easy decision. I enjoyed my time at Birmingham but relegation half made the decision for me. "I want to be in the Premier League and I'm sure everyone can appreciate that. "But I enjoyed my time at Birmingham." Johnson has made 88 appearances for Blues since moving to St Andrews from Cardiif City in the summer of 2009.
