Celtic were defeated in midweek when they faced Bayern Leverkusen, despite the fact they originally took a 2-1 lead, as they conceded twice in the final 10 minutes of the game to lose 3-2.
However, prior to that, the Hoops had built up an undefeated run of nine games in all competitions and that recent form had helped to push them back into the title race.
Ange Postecoglou has guided his team up to second in the league table with just four points separating them and league leaders Rangers at the moment.
Celtic were also able to reach the Scottish League Cup final recently, having defeated St Johnstone 1-0 via a James Forrest strike.
The Hoops were also able to pick up three points the last time they met the Dons, with an 84th-minute goal from Jota securing a 2-1 win for his team on the day.
Aberdeen have struggled as of late in the league, having lost their previous two matches without scoring once, adding further concern to their recent performances.
The squad have managed just two victories in their previous six fixtures, but so far this month they have been unable to secure three points.

The Dons followed up a loss against Motherwell by being beaten by Dundee United in a match that also saw Funso Ojo receive a red card.
At the moment Aberdeen sit just five points above the relegation zone and considering all of the teams below them have a game in hand, that is a gap that could end up shrinking.
Only Ross County have actually lost more matches than Aberdeen this season and the form needs to be improved upon sooner than later.
