The Scot, who felt his side looked jaded despite beating Middlesbrough at the City Ground on Saturday, said: "There are lots of discussions going on again about who is available and which positions we need to strengthen.
"We are looking at the type of people we can bring in and the type of money we might be looking at. All we are doing at this stage is gathering information and discussing things as staff. There is nothing concrete just yet, but we are planning things again.
"That never stops to a degree, you are always looking at how you might make your squad better. But there are serious discussions going on now about what we might be able to do.
"We are looking at who we might be able to take from certain clubs and what it might cost us to get them on loan."
