Keane has already signed Lee Martin, Damien Delaney and Troy Martin this summer and the former Sunderland boss is poised to strengthen further.
He said: "We have agreed a price with two players who I hope to meet in the next 48 hours.
"At Sunderland I spent about £6million when I first arrived, if I can spend about £6million here and get this team promoted I'll be very pleased.
"There is also the option of one or two loan players."
