It's been a busy window for Celtic but there's still time for plenty of movement before the end of the window.
Boss Ange Postecoglou has got the majority of his business done, securing five signings already.
There could be scope for another winger or left-sided defensive player but that could be dependent on Celtic moving some of their fringe players on.
One such player could be winger Mikey Johnston, who is a live option for Aberdeen.
Boss Stephen Glass is concentrating on pace in forward areas and the Scotland Under-21 international fits the bill.
As revealed by Record Sport Dons captain Scott Brown is a huge admirer of the Parkhead academy graduate and has offered up a glowing reference.
Celtic are also looking at potential exits for the likes of Vasilis Barkas, Boli Bolingoli and Ismaila Soro, while Adam Montgomery is close to joining Kilmarnock on loan.
The Parkhead club have moved early to secure their preferred targets, Postecoglou isn't ruling out more arrivals.
He said this week: "We will stay alert and agile, there still could be some things that happen.
"We're still looking at loans for a couple of our younger players so I'm sure there'll still be some activity between now and the end - what sort of activity that is, we'll just see how it all develops.
"From our perspective, our planning has gone to schedule so far and hopefully that continues to the end of the window."
