Redknapp has missed Spurs’ last two matches after undergoing minor heart surgery last month.
“There’s a possibility Harry will be back for the Villa game. He’s very keen and optimistic of that happening,” said assistant manager Joe Jordan.
“Hopefully he’ll be back soon. It will depend on his conversation with the medical people who are giving him advice.
“If he comes to the game he’ll be on the bench. If he’s at the stadium why wouldn’t he be on the bench making decisions and being involved?
“Against Fulham it would have been torture watching the game and not making substitutions or decisions. He will have suffered a lot more.”
