Celtic put their domestic treble credentials on the line as they entertain St Mirren at Parkhead.
There is plenty of intrigue in this fifth-round Scottish Cup tie between the two Premiership teams, particularly as Stephen Robinson's Saints can proudly boast that they are the only side to inflict a domestic defeat on Ange Postecoglou's men this season.
With the game being played to a finish there are no second chances in the competition and the Hoops know they must advance if they are to keep their bid to go one better than last season on track.
Who will the manager pick? Our writers have their say...
Tony Haggerty
There's very much a school of thought that there is nothing to change about at the Parkhead side's team at the moment.
Postecoglou rarely plays the same team twice in succession, as it is all about squad rotation with the Aussie.
That being said we are now approaching the business end of the season and a potential domestic treble is on the line here.
Therefore Joe Hart will remain in between the sticks and there will be one change to the tried and tested back four which will see Yuki Kobayashi come in at the expense of Carl Starfelt to partner Cameron Carter-Vickers at centre-back. Alistair Johnston and Greg Taylor will fill the right and left back berths, respectively.
The manager really is spoiled for choice in the midfield and attacking departments but I feel Postecoglou will want to get the job done before handing the likes of David Turnbull and Tomoki Iwata precious game time. The triumvirate of Callum McGregor, Aaron Mooy and Reo Hatate will be trusted to start against St Mirren but they won't all finish the match.
In attack, Kyogo Furuhashi will be trying to eke out goal number 23 of a truly wonderful season for the Hoops and he will be ably assisted by Daizen Maeda on the left wing and Jota on the right.
Tony's team: Hart; Johnston, Carter-Vickers, Kobayashi, Taylor; McGregor, Mooy, Hatate; Jota, Kyogo, Maeda
Aidan Macdonald
Given this is a one-off game, it is unlikely that Postecoglou will take any chances with his team selection. Therefore he will name the same starting XI for the second match in a row.
Hart will start in goals as he is the number-one choice currently and Benjamin Siegrist remains out injured. The back four in front of him will remain the same as the one that played against St Johnstone. Johnston will begin at right-back with there being no real need to throw in Anthony Ralston. Carter-Vickers and Starfelt will continue their partnership in defence. Taylor will once again play at left-back.
In midfield, McGregor will anchor the team from the number six position as usual and both Mooy and Hatate will remain as the two eights in the middle of the park.
Upfront it will be the same three that led the line in Perth. Jota will begin on the right wing, Kyogo will play through the middle and Maeda will start off the left-hand side.
Aidan's team: Hart; Johnston, Carter-Vickers, Starfelt, Taylor; McGregor, Mooy, Hatate; Jota, Kyogo, Maeda
