Davies, who pulled up in the defeat at Bournemouth on December 5, returned to training this week but is now facing another "couple of weeks" on the sidelines following a recurrence of his hamstring injury.
“In the context of where we're at at the moment, I think it is an important [window],” Postecoglou said. “Our league position is not great but it’s super tight and we’re not that far off.
“There's still everything to play for this year for us to make it a season where we can have success. But we need some help, the players need some help more importantly, and the club is working really hard to try make that happen.
“It will depend where we’re at when the window opens and we're getting close to that now, so we've got a clearer picture of where we're at.
“I still think we have to be disciplined, it's not just about just bringing anybody in. There's certainly a need to reinforce if we can. Everyone knows January's not an easy time to do that. But the club's working hard behind the scenes to see what we can do to help players we've got at the moment who are giving everything in every game and dipping into every bit of energy they have to try to get us through.”
“At least two or three who are fairly long term injuries so you know you're going to be short there. Others are coming back from significant injuries and you don’t know how long they’ll take to get up to speed. We need some reinforcements and the club is working hard to make that happen and we'll see where we get to.”
“It is what it is. It’s not what motivates or drives me. My motivation for what I do is try to create teams who win things and have success and make an impact.
“It doesn’t add any pressure or I don’t feel any extra anxiety about anything. I firmly believe we will get through this and come out stronger and create the team we want to be.
“They made those feelings and emotions seen. I haven't felt anything but support since I have been here and I still feel that support is there.
“The task is difficult at the moment because of our situation but like most things that are fairly difficult to traverse, it's only temporary and we'll get through it and come out stronger.”
