Ange Postecoglou has made additions to his squad already this month as he looks to lead Celtic to the Scottish Premiership title.
His side have now closed the gap on leaders Rangers to just two points and can go top of the table midweek if they beat the Gers.
Celtic are unlikely to have any new faces in through the door before the derby though as they are letting it be known their incoming business is done.
The Bhoys could have a rethink though if a superb opportunity presents itself in the final hours of the window though.
While Celtic have completed their incoming business, they could ship players out today.
Several players could depart Celtic Park, while striker Albian Ajeti could head to Swiss giants Basel.
However, with the Swiss transfer window not closing today, Celtic have no rush to push through an exit for the former West Ham United striker.
