Celtic have gone into the international break on the back of successive wins after their narrow and rather unglamorous win over Kilmarnock on Sunday.

The Bhoys came out on top thanks to a first-half goal from Liam Scales, and combined with Thursday night's Europa League win, they go into the break with a very different feeling from the last international window.

Back in September, Celtic went into the break on the back of three straight defeats, and Martin O'Neill was left contemplating his own future. The Bhoys now have a moment's rest from the criticism, but some players will be worried about their position in this squad.

Here we take a look at the players who are at risk of being cut by O'Neill in the January transfer window.

Luke McCowan

McCowan has had a tough season so far, and it all started with his disastrous cameo against LASK in that infamous Champions League collapse. The midfielder was slaughtered by fans after that game, and some of it crossed the line into abuse.

McCowan has come back into the fray a little of late, making two substitute appearances in the last two league games, but it doesn't feel as though O'Neill fully trusts him, and this is not a young player.

McCowan is 28 years of age and he cannot get into a team that has a particularly poor midfield and a clear lack of depth in the middle. That is an indictment in itself, and we have already seen reports that McCowan could be offloaded if Celtic can find a replacement.

Anthony Ralston

The curious case of Mr Ralston. The right-back did well last season and even won World Cup spot with Scotland, but he has been missing since. Alistair Johnston has barely played, but it is Colby Donovan who has seized the opportunity to become the lead deputy,and to add insult to injury, Celtic went and signed another right-back in Jordan Lotomba, who has seen more starts than Ralston, who is yet to start.

Ralston does not have a single league appearance to his name, and he finds himself the fourth-choice right-back at this stage. He is out of contract in the summer, and it would be stunning if Celtic don't offload him in the winter window.

It would be best for both parties to move on, and it's clear that the right-back position is one of the few areas this Celtic squad actuall has enough depth.

Sebastian Tounekti

Tounekti has had a tough time of things this season. He has been heavily criticised for his lack of consistency, and for his predictability as a winger. He is somewhere between unable and unwilling to repeatedly run at and beat his men, regularly turning inside or taking the easy option.

The Tunisia international has talent, there is little doubt, but he has been given repeated opportunities this season amid injury issues on the left, and he has repeatedly fallen short of expectations. In fact, in 17 appearances across all competitions, Tounekti has one assist and no goals. That's just not good enough for a winger who plays for a team that generally dominate opponents domestically. Being a winger for Celtic, especially under O'Neill's direct style. should be a dream.

Fans have run out of patience when it comes to Tounekti, and it feels as though O'Neill's patience is also wearing thin. To make matters worse for the winger, Jota and Yang Hyun-jun are now nearing full fitness, while Callum Osmand has also impressed on the left.

O'Neill may feel as though he has enough on that side, and if the right-footed Tounekti isn't going to compete on the other side, a loan move, in particular, could be seen as a good option.
