The ex-Switzerland boss feels the reigning Bundesliga champions should act now and lure the Roma centre-back to the Allianz Arena
Pep Guardiola's side are in the market for defensive reinforcements after Javi Martinez was ruled out for the remainder of the calendar year with a knee injury.
"Benatia is the captain of Morocco's national team and he has a lot of quality," Hitzfeld told Sky90.
"In the end, it's all about whether he can help Bayern forward. Bayern need quality and should act now."
In preparation for Benatia's exit, Roma have had a £10.3 million bid for Kostas Manolas accepted by Olympiakos and are now finalising a deal for the Greece international.
