The Scotland winger's first foray into English football did not turn out well after a disappointing spell with Aston Villa in 2007.
Maloney returned to Celtic in 2008 and signed a four-year deal but the club appear willing to sell him again.
"Nothing concrete has happening as yet," Whelan told BBC Scotland on Tuesday.
"We're still talking to the club. If we get things tied up with Celtic then he'll come down for a chat tomorrow."
