Mark Warburton has made a number of appointments to his backroom team at Rangers already.
Flannigan arrives at Rangers as part of Mark Warburton's new-look backroom team, and he will be tasked with ensuring that the players are in peak physical condition for each game.
And, although Flannigan admits that a lot of good work has gone on prior to his arrival, he wants to put his own stamp on things.
“How long is a piece of string? There are a million and one things you want to do when you come into a facility like this," he said.
“There has been a hell of a lot of good work done prior to me coming in, and I see myself as an addition to that, and hopefully as the club moves forward over the season, I can install my methods into training, and hopefully that will enhance what has already been done.”
Warburton has been quick to recruit new members of staff, to further strengthen the coaching and scouting departments at Ibrox.
Flannigan will not want to change too much too quickly, though, as Rangers are clearly on the right track at the moment.
The Gers have been in wonderful form since the start of the campaign, and they have taken maximum points from their opening 10 Scottish Championship matches.
That winning run has accelerated them to the top of the table, and the Light Blues are looking near-certainties for promotion, even at this early stage of the season.
