Tuesday night was of course a disappointing one in terms of the result for Celtic, but first things first, let’s not forget they were up against one of the only teams who can genuinely win the competition.

Paris Saint Germain were sensational on the night, and they have real world-class players all through their team that they have bought for mindboggling sums that the likes of Celtic can only dream of.

Obviously the focus is on Neymar and Kylian Mbappe who are top drawer players, but it is quite something that the likes of Edinson Cavani, who was fantastic, and Adrien Rabiot, who was a real joy to watch and probably the best player on the night, are two who go under the radar a bit.

So, there is no shame in a team like that coming and giving you a bit of a thumping, even on your own patch where Celtic have been so formidable.

Having said all that though, I would imagine that Brendan Rodgers would still be disappointed in a few aspects of Celtic’s play, and not least of which would be their inability to get close enough in the midfield area.

A lot has been made of the lack of centre-back options and the failure to strengthen that area proving costly to Celtic at this level, but I don’t think another central defender in Celtic’s price range would have made that much of a difference in this particular game.

What might have though, was a greater desire from the midfield to stop PSG from playing their game.

Rabiot, as I mentioned, was absolutely tremendous on the night, but he had the cigars out because nobody in a green and white jersey was getting close enough to him to make a challenge.

And I think this is an aspect of Celtic’s play which will have to considerably improve if they are to make any headway in this Champions League group at all.

The problem that Celtic have is that they are so far ahead of every other team on the domestic front, that it is hard to make that mental switch into being the team who isn’t going to dominate the ball and is going to have to do the chasing.

When you are so used to dictating the play, especially at Celtic Park where they haven’t lost since last year’s Champions League, then it is difficult to then have the shoe on the other foot.

It is something that Celtic are going to have to adjust to though if they are to get results against the likes of Bayern Munich and even Anderlecht, who will certainly fancy themselves to have a fair bit of possession even when they come to Glasgow.

When you come up against such a high standard of team, sometimes you have to sacrifice a little and do the hard chasing and closing down that Celtic aren’t used to doing on a weekly basis, and particularly in the first half, Celtic just didn’t do that.

Now, of course, it is easier said than done. It’s not just as simple as working harder and clattering into challenges, and you have to give credit to PSG for their wonderful movement.

Even still though, I feel that more of an effort could have been made by the Celtic midfield to get in touch with their direct opponents and knock them out of their stride.

After half-time in the game during the week, things certainly improved, and it looked as though the manager had got that sort of message across.

And two players who really set the tone in that regard were the young full-backs, Kieran Tierney and Tony Ralston, who I thought were Celtic’s best performers on the night.

What Celtic can of course take heart from as well is the way they responded to the opening night thumping they took at the hands of Barcelona in the Nou Camp last year, and I wouldn’t be writing them off just yet in this group.

If they can get their pressing game going, then there is no doubt that they can take points from anyone.

In the here and now, I expect a huge response from the Celtic players in today’s encounter with Ross County.

There is always a danger in these sorts of games, coming just a few days after such a huge European night, that the atmosphere is a little flat and the players look a little drained.

But I would expect that more than a few of them will be hurting, and there will be a desire to be the ones this time to go out and put on a show for the fans.

I would expect Celtic to win comfortably, perhaps emphatically, as they look to get the disappointment of Tuesday evening out of their systems.
