Those Rangers fans who have voiced their opposition to his recruitment, on the basis of both his career goals-per-games return and his 13-month spell as a Celtic player under Gordon Strachan, will require considerable convincing of Miller's worth.
"I am absolutely delighted to sign for the club again, the smile has not come off my face yet. It has taken a little bit longer than we expected, but it was an easy decision for me to make.
"When a club like Rangers comes calling, then it is always going to be difficult to knock that back anyway, but the fact I have worked with the manager and Ally closely before definitely helped.
"I get on well with them on and off the pitch and they seemed to get the best out of me with the national team, so hopefully that will continue in the new season with Rangers."
Miller is only the second player to cross the Old Firm divide twice to play for both Rangers and Celtic, following defender Tom Dunbar who moved from Celtic to Rangers in 1891 before rejoining the Parkhead club the following year. Miller is the first to rejoin Rangers after playing for Celtic.
"It was a learning curve for me being at the club before," Miller told Rangers World, "but it is eight years on now and I feel a lot more experienced and a lot more confident coming to a club like this.
"As a player, you are always looking to progress and develop and when you play in the Champions League or at international level, you gain experience in the process. I definitely feel I am coming here a far better player than when I left first time around."
Miller scored just six goals in 33 appearances for a dismal Derby County side who were relegated from the Premier League last season.
