With a 7-1 win over Hearts at the weekend, Celtic have every reason to be confident going into their matchup against Celta Vigo this week, even though they have lost both their Europa League matchups so far.

That does mean that Celtic are under pressure to get a result against Celta Vigo. If they fail to do so, it would make qualification to the next round of the Europa League very difficult.

Unfortunately for Celtic, two of their key players have already been ruled out for their game against Celta Vigo.

We have already talked about Yang Hyun-jun not being fit in time to take on Celta Vigo this week. Unfortunately, he is not the only one in that situation.

Another Celtic player looks set to miss game against Celta Vigo

Cameron Carter-Vickers is another player we have not seen in action over the last few matches for Celtic.

Carter-Vickers grabbed the headlines with his comments following Celtic's loss against the Rangers right before the international break. A lot of fans would have been intrigued to see if that would end up having an impact on his place in Martin O'Neill's plans. But due to an injury, he has not even been available since then.

As reported by The Celtic Way, O'Neill said when asked whether Carter-Vickers would be available to face Celta Vigo: "Cameron, I think the earliest we'd be probably seeing him would be the Hibs game."

So, this is another game that Carter-Vickers is not going to be available for. And Celtic could have done with his experience on the day.

Who will start at centre-back for Celtic vs Celta Vigo?

Dane Murray earned a lot of praise for his performance against Hearts at the weekend. So, it is quite likely that he is going to be the one starting against Celta Vigo as well.

On the other hand, it might be a toss-up between Auston Trusty and Liam Scales in the other centre-back position.

Trusty had played the entire 90 minutes against Benfica, while Scales did the same against Hearts. So, it does look like O'Neill wants to stick to the left-footed, right-footed centre-back combination.

If you asked me, Scales is most likely to retain his place in the starting XI after the one-sided win against Hearts.

When it comes to Trusty, his combination with Murray did not really work when the two started against Benfica last week. The Celtic defence proved too easy to get through for the Portuguese side, who scored four goals and could have easily had a few more if they had been a bit more clinical with their finishing.

Then again, one cannot rule out the possibility of O'Neill deciding to rely on experience and going with the Scales-Trusty duo, which was his preferred setup for most of his last season.
