Pennant, whose last club was Tampines Rovers in Singapore, is under contract at Bury for the rest of the season.
And he told The Sun: “I could have earned five times more by staying in Asia.
“But I was away from my family for a year, which was hard for them.
“My agent knows the Bury gaffer, Chris Brass, very well, and they said come and give it a go.
“The decision was made and, if my wife's happy, I'm happy."
