Glasgow and Manchester derbies clash - which one will you be watching?
The football scheduling gods have - in a rare case - come up with a clash of almighty proportions with both the Manchester and Glasgow derbies clashing.
Saturday's Old Firm - the first in the league since Rangers relegation to the lower leagues - kicks off at noon while the Manchester derby kicks off 30 minutes later.
For some it will be a huge weight on their shoulders as to which game they watch.
But what will you be watching? Take part in our vote:
In Glasgow Brendan Rodgers will experience for the first time the Parkhead atmosphere of an Old Firm tie.
While in Manchester, Jose Mourinho and Pepe Guardiola will resume their hostilities in their respective new jobs.
For one supporter of both though the answer is easy.
"It has to be City," Rangers and Man City fan Ricky Beresford said.
The Enniskillen man has worked in both cities.
He said: "It used to be all Rangers for me, but after living and working in Manchester it is always Manchester City now.
"The Old Firm has the passion. But when you compare Kolo Toure with John Stones, Leigh Griffiths with Zlatan and Joey Barton with David Silva there is no comparison."
Ricky has worked in the game for both Dundee United and Linfield. He was at the last league game between the Glasgow giants and turned down a ticket for Saturday's game.
He added: "There were rumours at the time the last game - a 1-0 defeat - may be the last for a while. And it turned out that way.
"I'll still be interested in the game. I'll stay off social media and watch the Old Firm game straight after the Manchester derby.
"Mark Warburton is a clever guy, but I think Celtic have, in Brendan Rodgers someone who will make sure Celtic win the league.
"Celtic will win it by at least a clear goal - provided there are no red cards.
"In Manchester Mourinho will send his team out to kick us - but we'll win it 2-0 or 2-1."
