Ange Postecoglou will be looking to strengthen his squad during the January transfer window and although it's notoriously difficult time to sign good quality players it hasn't stopped Celtic in the past.
Tomoki Iwata, Alistair Johnston and Yuki Kobayashi have already signed for the league champions, but the Aussie gaffer has hinted on a number of occasions that more could be heading to the east end of Glasgow before the window slams shut at the end of the month. Speaking last month Postecoglou said if a player becomes available then "we will move on it". He added: "We will see what January brings. My view on these things is that, if a good opportunity comes up that will make us stronger, and it makes sense for us, then we will move on it."
Many managers bemoan the winter window, however there can be bargains to be had and that has proved to be the case for Celtic in the past. Whether it is players looking to reignite their careers, such as Robbie Keane, or those who are taking the step up to the next level like Barry Robson the January window has seen it all.
