An inability to put down roots has prevented Routledge from showcasing his true potential in the past, with a nomadic existence taking him from Crystal Palace to Swansea via Tottenham Hotspur, Portsmouth, Fulham, Aston Villa, Cardiff City, Queens Park Rangers and Newcastle United.
The 27-year-old appears to have finally found a suitable home at the Liberty Stadium, and stability off the field has brought success on it - with the tricky winger having netted twice already this season and laid on several assists.
On the level he has been able to hit on a regular basis, Routledge said: "For me, on a personal note, it's going well - I'm playing games, making chances and scoring goals, so I can't ask for much more.
"People can ask you to pinpoint what it is, but I'm not sure. I'm playing more and that's probably given me a bit more confidence and now you're seeing the best of me.
"It's definitely up there (with the best form of my career), I'm enjoying my football every time I step out on the pitch and every time we train.
"That's a nice feeling because that's when you get the best out of players.
"I just want to keep playing well, keep making chances and maybe keep scoring more goals."
Next in Routledge's sights are Manchester City, with Swansea hoping to catch the reigning Premier League champions off guard following their shock midweek defeat to Ajax in the UEFA Champions League.
Routledge added: "The Etihad has become something of a fortress for them there, but we've got to go there in a positive frame of mind.
"As footballers, they're in the higher echelons but sometimes you have games when it doesn't click.
"That seems to be what happened the other night, it wasn't the usual Manchester City.
"But when you play Manchester City, whatever they do it's going to be a really hard game on Saturday. We have to get our minds right and be ready from the start."
