Scottish League/Motherwell v Celtic: Martin O'Neill has dropped the biggest hint yet that he will not be manager of Celtic next season and there is now a real possibility he will leave Parkhead within weeks.
By then he could have led the Glasgow giants to both the Premier league title and a Scottish Cup to take his tally of trophies to eight in his five years in charge.
Beyond this weekend and next, though, lies a future that seems destined to include time out of the game in the form of either a sabbatical from Celtic or a clean exit.
O'Neill seems to have been paving the way for a departure of some sort. Last night he said: "If you're asking me if I am going to another football club the answer is no." But he later added: "There is as good a chance of me being here next season as not."
That left the door open to what many believe will be a six-month absence prompted by the illness of his wife, Geraldine, which has been a cloud over him for the last year or so.
If he does go there appear to be two possibilities. He could leave behind the current assistants, John Robertson and Steve Walford, to run affairs until his return. Or there could be a complete change of management.
If a new management team is drafted in it may even have an impact on other clubs. Should Manchester United not start next season in full flow then Old Trafford may yet beckon.
Newcastle and Graeme Souness seem to have a potentially uneasy relationship and the Scot needs to hit the ground running next season. Any moves could prompt O'Neill - if he has taken time out - to return to the game.
The latest debate about O'Neill's future comes as his team contemplate a win over Motherwell, which would give them their fourth title of his tenure, regardless of what Rangers do against Hibernian at Easter Road.
Then, next Saturday, comes the Cup final against Dundee United. O'Neill, trying to focus on football rather than himself, addressed the trip to Lanarkshire and gripes about injured players from rival manager Terry Butcher - Motherwell will be without at least five first-team regulars.
"I don't think Terry has ever approached a game in a laid-back manner. Next he'll be saying he's phoning in from some beach to apologise for not making it. The players expect it to be tough."
Rangers must beat Hibs, who need a point to make it into the Uefa Cup, and then hope for the best, while today Livingston and Dundee, who meet at Almondvale, and Dundee United, who face Caley Thistle in Inverness, try to avoid relegation.
