Tim Cahill has shared his delight after sealing an emotional return to the club he calls 'home'.
The 38-year-old forward put pen-to-paper on a deal that will see him at The Den until the end of the 2017/18 campaign on Monday afternoon, with Cahill stating that it was "hard to put into words" his feelings on signing for The Lions once more.
"It's an amazing feeling," he said. "To finally come home and to join Neil Harris, David Livermore and all the lads will be really special. I can't wait to greet the fans, meet my new team-mates - it's one of those things where it's meant to be.
"It's hard to put into words [what it feels like to wear a Millwall shirt once again]. I'm still taking it in now. The first thing I wanted to do when with Neil was to walk on the pitch and in the tunnel and have that feeling again that brings back so many memories.
"Once you go over that white line, you get a nervous sensation back that I had when I was a 16-year-old when I first signed here."
The Aussie international makes no secret of his desire to secure a spot in The Socceroos' 2018 World Cup squad, but also realises the "romance" of the story that has seen him return to his old stomping ground.
"I'm really happy. I've had a great career as a footballer, but to come here now at this stage of my career, with eyes on a World Cup place, it's such a professional environment. It's familiar. Not much has really changed, which is surprising, but it's nice to come back to where I was as a kid.
"The romance of the story is definitely not lost on me. I've always said that if I came back to England, I'd come home. Millwall is where I learnt my trade and it was the most important learning period of my life - my apprenticeship in understanding football.
"To come home to where it all started, it's emotional, but it's happy emotions, because you wish for it to happen, you want it to happen, but when it finally comes to fruition, it's the perfect move."
Cahill went on to explain how despite embarking on a career that took in countries such as America and China, he always "stayed in touch" with his roots.
"I use Millwall as an example to any footballer. If you can play at Millwall, you can play anywhere. I stayed as long as I could before moving on to the Premier League. There's a whole understanding to playing for your club - it's a responsibility for your fans. The connection with your fans is the most important thing for me. With social media today, they've stayed in touch and I feel like I've never been away.
"I've followed the highs and lows and what Neil has done with the football club. The stability, the infrastructure and the vision moving forward in what they want to achieve - I'm really proud of everyone at the football club. More importantly, and to me as a player, it's all about the fans. The loyalty side which I've consistently had throughout my career. It's really special.
"I was really impressed with the way Neil and David Livermore conducted themselves when we spoke. Yes, we're mates, but it's also business. He understands that it's a results game for him, but I also understand that there's levels that need to be met."
The Aussie also explained how far he feels he is from a return to first-team action.
"It's just training - getting back to training. It's all about infusing myself into the squad as soon as possible and working my way to the levels the players are at now. At the moment, I'm ticking all the right boxes, but I'm not putting any parameters on it, because any footballer that signs for a club, no matter how long you've been off, if you're on the bench tomorrow then you're never going to say no."
