Keith Curle is looking to add to his squad before the start of the new season with the centre of defence a particular area of focus.
“We have got targets in mind,” he said.
“We’ve known for the last two or three weeks that Aaron leaving was a possibility and because of that we’ve been able to identify our targets.
“I need to bring maybe two centre-backs in order to give us proper balance and cover.
“The sooner we get our business done the better but we don’t rush into things and we are prepared to wait. As with all our signings this summer we need to make sure that everything is right.
“We still need to show good housekeeping. Value for money is important as is making sure we bring in the right characters.”
