Mikael Lustig should return to fitness for Celtic before the end of this month, which will offer Celtic boss Ronny Deila a poser about whether he goes straight back into the starting line-up.
Lustig is an experienced defensive option to have coming back into the team at an important stage of the season, but there are other options for the manager if he feels he needs to hold Lustig back.
Deila has created a mentality at Celtic that all players have to work hard to justify their positions in the first team.
That’s common sense and suggests that someone like Adam Matthews, suffering from a less severe ankle problem, should be confident that he’ll keep his place in the side.
There’s also the risk of complacency if Deila opens up the team to allow him straight back in.
Even if Matthews misses the cup game against Dundee United this weekend, the theory doesn’t change because of the extra option Darnell Fisher gives the manager.
The circumstances where Deila may consider putting Lustig straight back into the starting line-up aren’t worth thinking about for Bhoys fans.
For Deila to drop players, make big calls and take tough action on players that have been consistent and working hard for the club, some sort of defensive capitulation will have to take place.
That seems extremely unlikely considering the cushion Celtic have in the title race despite their defeat to St Johnstone earlier this week.
Cup games are cup games where anything can happen over 90 minutes, but Lustig’s immediate return to the starting XI for any Scottish Premiership game would more than likely need an out of character disaster occurring across the backline.
