McFadden has made big-money moves to Everton and Birmingham as well as making a return to Goodison Park last season and having a spell at Sunderland this term.
But his signing for first club Motherwell has been hailed as the return of the prodigal son by many fans.
McFadden, who scored 32 goals for the club as a teenager, made his comeback in claret and amber in the 73rd minute of the 1-0 defeat by Dundee United on Tuesday.
And he is desperate for more game time in order to meet his and the Motherwell fans' expectations.
The 29-year-old, who has only made 12 first-team appearances since suffering a cruciate ligament injury in September 2010, said: "This is probably the move where I've had the most expectation on me so in that sense I've got everything to prove.
"I've had a bad injury and had a tough time since then and maybe people are starting to doubt that I can play to the level I was at before, so I think I've got more to prove in this move than any other move that I've made."
McFadden, capped 48 times by Scotland, is set to start on the bench again in the Clydesdale Bank Premier League clash with Ross County on Saturday following his first competitive Motherwell appearance since 2003.
"It was great," McFadden said. "I could have been doing with a wee bit more but it was nice. I got a great reception from the fans.
"Obviously it was disappointing we never won the game or got something from the game but Dundee United were good on the counter-attack, so you have to give them credit."
