THE bulk of Celtic's January transfer work has been done, according to Ange Postecoglou.

The Hoops are looking strong to retain their Premiership crown this season as they sit seven-points ahead of Rangers in the table.

A big part of their success has been Postecoglou's eye for a player, with very few signings under his watch not making an impact on the first team.

Fans will be excited to see what gems he manages to unearth in the upcoming winter window.

The Australian has revealed that nearly all of the planning work for that has been concluded.

He told the media: "A couple of weeks ago, we sort of did our (transfer) planning. The bulk of the work's been done.

"What this time gives me is a little bit of opportunity just to plan for the rest of this year and probably the next summer window."

Celtic face Motherwell and Ross County before the mid-season World Cup break over the next five-weeks.

And Postecoglou wants to see his side earn some much-needed time off with two victories.

He added: "We need to get through the next two games nice and strong.

"We've had a really solid block of games. Champions League results aside our performances have been really strong through that and our league form's been excellent.

"My gut tells me it's probably a good time for the break because we've had just so much football in a short space of time. As much as the players have got through this period, there's always a tipping point - not just physically but mentally."
