Celtic manager Neil Lennon must pick between Jeremy Toljan and Mikael Lustig for Sunday.
The Hoops play Aberdeen at Hampden in the Scottish Cup semi-final.
The treble treble and the season is on a knife edge as a poorly performing Celtic team play the sturdy Dons.
Every decision will be scrutinised by fans, and Lennon must make sure every one is the right one.
Mikael Lustig winning the battle?
The Swede has been a mainstay in the Celtic squad for the past few years but performances have dipped.
Toljan came in and was a brief starter but the 32-year-old is slowly regaining his place.
The German’s defensive ability isn’t as strong as Lustig’s, though his youthful stamina and speed gives him a greater attacking dynamic.
However, as the Dons have tricky wide men, the defender’s job first and foremost is to keep him quiet.
Lustig is a better player at doing that and does use his experience well to position himself.
However, in a leg race more often than not the Aberdeen winger will win that so he must be backed up by his centre-backs.
However, Toljan’s defensive abilities will offer more opportunities to Aberdeen.
Jeremy Toljan not the man for a cup semi
This is arguably The Bhoys’ biggest game of the season as the campaign depends on it.
Toljan gets caught when wingers go past him and often receives yellow cards for it.
He is less disciplined than Lustig when it comes to this and we’ll need all our men on the park.
To lose discipline and numbers in the semi-final will only be detrimental to the team.
They are two men in different parts of their career and this is another aspect where Lustig shades it.
If Lennon chooses Toljan then he is putting the result at risk as Derek McInnes will have him worked out.
These decisions are what show good managers are and if Lennon wants the permanent job he must make the right choice.
