Leigh Griffiths will determine himself just whether or not he is able to push things so that he can play against Rosenborg next week.

We don’t know the extent of the calf strain from which he is suffering but we can be sure that he will be given every possible chance to get himself out there. Much will come from his willingness to maybe get out there and play through it, if possible and depending on what risk that might create.

I think we all know that Celtic struggled against Rosenborg this week without an out-and-out striker.

And whether or not Griffiths makes it, the tie is 50-50 in the balance at this minute.

I don’t actually now when Griffiths picked up the calf injury – I hope it wasn’t when he was tying a scarf to a post.

Still, while we wouldn’t have thought it before the game the fact is that 0-0 ended up being a decent scoreline for Celtic. Given the chances that Rosenborg created, it was vital that Celtic didn’t concede as it looked more and more unlikely that they were going to score.

I felt that it would have been worthwhile bringing in additional striker this summer and I have said that long before this scenario unfolded.

I can understand that it is all about trying to maintain a certain balance in the squad and to ensure that there is the game time to keep everyone happy. Last season with Patrick Roberts there was someone there who could deputise when both Dembele and Griffiths were out, but that option just isn’t available now.

To my mind, it would be sensible to have a little more cover in that position.

Still, although it wasn’t the result Celtic wold have looked for before kick-off, all is not lost. They are capable of going over there and scoring – and a score draw will take them through – but the performance will need to come up significantly.

So much, too, will depend on Griffiths and whether he is able to get out and lead the line. I would suspect that if he does make it then he ought to be fit enough.

He played regularly towards the end of the season and was then involved in international football up until the middle of June so you have to think that he won’t have lost a huge amount of fitness in the last few weeks.

The Sunderland game tomorrow afternoon might actually give an indication of what Brendan Rodgers might be thinking about his team selection ahead of the return leg. Any sight of Griffiths at all in this one and you can expect that he will be up for the game against Rosenborg.

If he isn’t going to make it, I would think it improbable that youngster Jack Aitchison might be thrown in purely because of the pressure it might put on the boy and because of his inexperience. However, if he is given some game time against Sunderland this weekend then it may well transpire that it is something that might be given some consideration given the paucity of players who can play up there.

I am not sure whether Rodgers will want to give some players a breather as he looks to avoid further injuries or whether or not he will look upon it as a further opportunity to get a bit of match practice in.

For me, while the lack of an established striker had a considerable bearing on the game on Wednesday night, I don’t think you can underestimate how much sharper Rosenborg looked. It is difficult to downplay the difference between being halfway through your season and just starting out into one as Celtic are.

I really felt that there was a massive difference in fitness and match sharpness, which is somewhat inevitable given the differing schedules of the two leagues.

It is one of the great frustrations of having to go through the qualifiers that you run the risk of that – and at this stage of the season it is definitely notable.

If the personnel are essentially the same for the return leg against Rosenborg then there will have to be a change in the way that Celtic line up as Rogic up front didn’t gel. However, while that has taken up a lot of the focus, I also think you need so much more from those in the middle of the park.

They need to offer much more in the way of support.

Rosenborg won’t actually play too differently at home than they did in Glasgow. They will play much the same style and although Celtic are capable of going there and scoring, they need to lift it considerably.
