Lee Croft says the prospect of teaming up again with St Johnstone manager Steve Lomas persuaded him to move to Perth on loan from Derby County.
The 26-year-old midfielder was at Carrow Road when Lomas coached the Canaries' youths and he also worked with assistant Tommy Wright.
"Knowing them as I do, I was keen to pursue the opportunity," said Croft, who has not played for the Championship side since October.
"I'm looking forward to getting games."
Croft began his career with Manchester City before heading to Norwich for £600,000 in 2006 after a loan spell with Oldham Athletic.
He switched to Derby in 2009 and was loaned out to Huddersfield Town last season but is looking to become a regular performer in the Scottish Premier League for the remainder of the season.
"I've only ever heard good things about the SPL from the guys I have played alongside who have actually experienced it and I was aware that Saints were having a good season, sitting well up the league table," said Croft.
"I'm hoping that my work ethic and experience will help us continue that good form for the rest of the campaign."
Croft will be in contention to make his debut against Hibernian on Saturday should he receive international clearance.
