Moussa Dembele's head is away. The way he behaved after being substituted on Saturday perhaps proved that.
This was something that I didn't pick up on until I got home. The fact that he got substituted in an Old Firm game — and went straight down the tunnel, got a shower, put his tracksuit on and only then came back out.
Now, if Rangers had scored the winning goal against us when I was in the shower all the players would have been having a go at me after the game.

Quite rightly, they would have been asking: 'Where were you? Why weren't you supporting your team-mates? Why weren't you out there watching the game on the bench?'
Look, if Celtic were winning 4-0, you could imagine the coaches saying: 'Listen, Moussa, you've done your job mate. Brilliant. Go grab a shower and come back out.'
But other players in that Celtic dressing room are right to say: 'We're playing and trying to win a game here. And you're in there having a shower, getting changed…'
From a player's point of view, I wouldn't like it. If you are injured, yes, you go and get an ice pack on. But it made me think. Is he that bothered? Is the intent there? Is he that bothered about the result?
I infamously had my own dugout incident in 2015 after being substituted against Molde in a Europa League game. I regret it to this day and made a public apology for the disrespect I showed to the management team.
But on Saturday, Dembele was disrespecting his team-mates.
Perhaps his head is away and he wants to leave. That really struck me — that probably his time is up. I think there will be little rumbles in the changing room, because it was very, very strange that he did it.
If any other player did it… if Leigh Griffiths did it, for instance, all the talk would have been: 'Oh, he's not happy, he's come off…'
Moussa was back on the pitch with his tracksuit on, clapping fans while wearing a hoodie. I'm thinking: 'What the …?'
Your team-mates are out there playing against their fiercest rivals in Scotland.
And you're inside showering up, putting your aftershave on?
I just think, from a player like Griffiths' point of view, Leigh has had to sit there watching from the bench.

You get on — and the first thing in Moussa's head isn't to sit and watch the game, but to go and get showered up. I thought it was very, very strange.
But if his head's away, it shows me that he's not all that bothered by the outcome of the game.
Whether we are reading too much into it or not, I don't think the players will be very happy with Moussa doing that while a game of that importance is going on.
It obviously raises the important question of what happens next. First of all, I need to say that Moussa is a terrific prospect with all of the attributes to be a top, top player — if he's playing every week.
He's had a few injury problems with his hamstrings. But, from a development side of things, Celtic are still perfect for him to learn his trade.
Brendan Rodgers is such a good manager that, if he stays, Moussa can keep on improving.
But if he feels that he wants to go and play in the Premier League and the money is right, nobody is going to stand in his way.
If he wants to go, there's no point in holding on to him — provided the price is right.
I'm sure, if a bid comes in, Brendan, Peter Lawwell and the chairman will consider all the factors.
