Gary Mackay-Steven has struggled to make an impact for Celtic so far this season.
It's fair to say that this season has not gone according to plan for Celtic so far.
Ronny Deila's side have crashed out of the Champions League in the qualification stage for the second season running, and they are also trailing Aberdeen in the league.
The Bhoys have looked well off the pace, and their demise has been surprising given the vast improvements that they made over the course of last season.
Celtic seemed to grow under Deila's stewardship during the 2014/15 campaign, where they won the double, and there were expected to go from strength to strength this time around.
However, they appeared to have regressed over the summer and their performances have been insipid and lacking in ideas.
There are not too many Bhoys players who can feel satisfied with their performance levels at the moment, but the teams struggles have been personified by Gary Mackay-Steven.
Brought in from Dundee United in January, the winger looked to be a real weapon after arriving, but his recent form has been alarmingly poor.
Mackay-Steven appears to be very low on confidence, despite having a highly impressive pre-season, and it may have got to the point where Deila needs to take the 25-year-old out of the team for his own benefit.
At the moment, he does not seem to have the confidence to take on defenders and his fragile confidence is being diminished by the game.
Although Celtic do not have a wealth of options in wide positions, Mackay-Steven needs to be replaced by one of Deila's other options, with James Forrest the most suitable candidate to take his place in the first-team.
A rest would not only benefit the player, but the team too, as both individual and club look to re-find their top form.
