He's really looking forward to coming here and we're looking forward to seeing him play," he added.On South Africa skipper Mokoena, Hart added: "Aaron's a strong player who bites in the tackle and he's the sort of character we're going to need in the coming months.
"I watched him play for South Africa in the Confederations Cup over the summer and he did great.
"He can play in defence or in midfield but I mostly see him as a midfielder.
"We've done extremely well to get him here. I'm really pleased that he's joined.
"Both Steve and Aaron have got plenty of experience and they're both very good players."
