Leigh Griffiths has answered every challenge that has been put before him at Celtic and it looks as though he will need to roll his sleeves up and get ready to do it again.

The striker missed Saturday’s game against St Johnstone with a calf injury which must be a source of frustration for him.

I thought he started the season on fire and had a real purple streak of form.

He looked fit and sharp and while I think that most of us would say that when fully firing on all cylinders that Moussa Dembele is a force to be reckoned with, the form of Griffiths this season has given Rodgers food for thought.

With Dembele back in the team, Griffiths will know that he needs to get back on it in order to get himself back in there.

But if you could say anything about Griffiths is that he has never sat back and accepted things if they weren’t going for him.

In some ways he might actually benefit from this period and getting in a bit of rest.

As soon as this week’s international break is over and domestic issues come to prominence, it is a hectic schedule right through until January with midweek and weekend games all the way.

This is when the likes of Scott Sinclair can take a break and hopefully find the kind of form that he was in for much of last season.

It also gives player like Patrick Roberts the chance to get themselves back to fitness.

The game last night saw many of the Celtic players involved but in any friendly I think you lack the intensity and pressure of an encounter when you need to win a game.

Although the Celtic lads are in every corner of the globe on international duty the clutch of Scottish boys will be back in at Lennoxtown with their eyes on a pretty significant six week spell.
