Sligo Rovers host the league champions in what is the big top of the table fixture of the weekend, live on television on Saturday (kick off 1:45pm).
The Hoops will be looking to get back to winning ways, having drawn their last three games, though they have lost just once from their opening ten (that the 5-1 hammering at St. Patrick’s Athletic four weeks ago).
The Bit o’ Red have a five-point advantage over the Hoops after 10 matches having maintained an unbeaten start to the campaign.
Sligo have won the last three games between the teams with every match last season proving a very tight affair.
Alan Keane is back for Rovers after overcoming a knee problem. Joseph Ndo is a doubt with a hamstring complaint.
Sligo manager Ian Baraclough said: “Both teams will look to win the game. The matches last year were very close and I think it could be quite cagey to begin with.
“It was important we had a positive outcome against Drogheda last week after the draw with St Pat’s. We did it without one or two key performers and I was very pleased with it.
“I don’t think Shamrock played particularly badly against UCD but 2-0 is a tricky lead sometimes and UCD fought back. They will have the same attitude as when we went to Drogheda, wanting to bounce back with a big performance.
“The changing kick-off times have not suited the supporters or the club and this week is something the players have to adjust to. The Showgrounds is at it’s best on a Saturday night but I know the fans will try to get behind us as best they can and hopefully they’ll see a good game between two of the best sides in the country.”
