A player can be deemed surplus to requirements for a variety of reasons. Some can be capable enough, but lack consistency. Others may be victims of having quality team-mates. And then there are those who are, quite simply, not good enough.
Celtic have used no less than 30 different players so far this season.
While most have contributed, with varying degrees of quality, to the Hoops' unbeaten league run, there are nonetheless several first-team members who are expendable.
Not necessarily "dead wood"—to employ the immensely popular footballing idiom—but dispensable nonetheless.
Here we take a look at Celtic's first-team squad members, including loanees, and suggest some of the players Neil Lennon's side could do just as well without.
As always, feel free to leave a comment if you feel any of the choices are misguided, someone glaringly obvious has been missed out or the analysis has been too disparaging (or hasn't been damning enough).
