The ex-Bianconeri official wants the Turin club to sell Mirko Vucinic and has suggested that Alessandro Diamanti would be a great addition to their strikeforce
As Goal recently revealed, the Biaconeri have agreed terms "in principle" with Higuain, with the Argentine currently considering parting company with Real Madrid after six years at the Santiago Bernabeu.
However, Moggi is set against the proposed deal, telling Radio Sportiva: "He's good player but he has no a champion."
Moggi also claimed that Juve can do without Vucinic, who has, for the most part, been the one constant in the Bianconeri attack this season.
"They have sold players given [Fernando] Llorente has already [effectively] arrived," he argued, referring to the Spaniard's summer move from Athletic Bilbao to Turin. "So they should continue to sell players that have been made redundant, maybe [even] Vucinic."
Moggi believes that Juve will not have to look too far for replacements, arguing that they should bring in Italy international Alessandro Diamanti from Bologna and teenage sensation Domenico Berardi from Sassuolo.
"Diamanti has proven himself to be a player who decides games," he enthused. "And also that he has the right DNA for Juve: he is a warrior.
"Obviously there is a need for a more competitive squad because the current players have been overworked.
"A publicly-listed football clubs must do be prudent, to comply with budgetary constraints and create value. But maybe [they should] take a young player like Berardi, just as they did with [midfielder Paul] Pogba."
Moggi would also welcome the return of Zlatan Ibrahimovic, with whom he enjoyed an excellent working relationship.
"Zlatan is the greatest guy in the world," he enthused. "He never had a problem with me, partly because there was a very clear relationship between employer and employee.
"He's a businesslike person. He adapts to the will of the employer on the assumption that they know how to handle things."
Moggi parted company with Juventus in 2006 because of his involvement in the 'Calciopoli' scandal.
