"I want to come to Hertha as I am not getting a game under the manager here," the out-of-favour Moroccan told Bild.
"I am on a good salary here so Villa will be glad to offload me.
"I would like to play for Hertha. It is a big club and my family lives in Metz which is just 20 kilometres from Saarbrucken."
Hadji, currently on trial with the German outfit, rejected a two month loan deal with West Ham earlier this month and is resigned to leaving Villa come the opening of the transfer window in January.
