Rodgers will make a big show of contrition in that first presser I bet, saying how he regrets how he left
The angle he'll need to work is that he realises now that he should have seen out the season before going. That's always been the sticking point for Celtic fans as far as I can see
They weren't mad he left, just mad at when he left them because it was mid-season and left them in potential disarray
If it's one thing Brendan Rodgers can do well, it's spin a yarn and tell people what they want to hear
He can show up at the presser and say that he feels he has unfinished business and that he wants to give back to the club to make up for how he left the first time
He'll sweet talk them and all will be well
Say what you want about Rodgers (and there's a lot you can say) but he understands how that aspect of the game works and he usually does well at it. It's all about telling them what they want to hear
