Shamrock Rovers have opened the doors of Tallaght Stadium to allow their European opponents, AC Milan, start their prep work for that massive Europa League tie in just 12 days' time.
But the Hoops plan to give nothing away to their domestic rivals Bohemians when the two clash in a top of the table battle behind closed doors at Tallaght Stadium today.
The shortened nature of the 2020 season due to Covid-19 leaves very little margin for error in the title race, as second-placed Bohs know that a win today, and then eight wins from their last eight games, would earn them a first league title since 2009, while Rovers are aware that victory today would give them a five-point cushion for the run-in.
Along with that title chase, Rovers have to cope with Milan in Dublin in that one-off, second-round tie. Milan's General Manager spent time in Dublin this week inspecting the stadium and hotel facilities, but as far as manager Stephen Bradley is concerned, their scouts won't get in to today's game.
"I'm not sure they're allowed, to be honest," says Bradley, joking that his own request for a 10-day stay in Milan to scout out Zlatan Ibrahimovic's club didn't come to pass.
His focus is very much on the derby today, more than the usual dose of bragging rights on offer.
Rovers striker Greene was at Bohs in 2010 when they were reigning champions and had their title taken away by Rovers, and in his two spells at Rovers, this is the first time they have been title challengers and he enjoys that.
"It's great," he says. "It's just a pity that there is no one going to be at it. I'm not surprised at Bohs, they are a really good squad. Look at their results. They might not play the way we do but they win games and that's all that matters. They are a threat.
"Bohs are there on merit, same with ourselves, and we don't want to give up top spot to them. If they come up and beat us, they go one point clear and that's something we don't want to give up."
Greene says the league won't be decided today. "I don't think the title is going to be won or lost. It's too early in terms of that," he believes, insisting that Dundalk are still in the race.
Bohs rested most of their first team for Monday's FAI Cup win over Cabinteely, rare outings for players like Dinny Corcoran and James Talbot but Keith Long has a full deck to pick from for today's game.
