Sligo Rovers manager Ian Baraclough says his side needs to up their game if they are to maintain their incredible start to the season.
Rovers made it 10 wins from 10 games so far this year, with a 2-0 defeat of Cork City at the Showgrounds on Saturday.
Lee Lynch and Anthony Elding got the goals in either half, with Elding's strike already taking him into double figures for the season.
But Rovers have to play St Patrick's Athletic, Drogheda United, Shamrock Rovers and second-placed Derry City over their next four league games, while also playing the Louth men twice in the Setanta Sports Cup semi-final.
And Baraclough believes that Saturday's display won't be good enough.
"I hate criticising the lads when we keep winning the games. Certain parts of the game were good, but at times we weren't switched on enough and we need to be because the run of games we have got coming up are going to get progressively harder.
"It's enough having a decent side playing against us. If we also go and make it hard for ourselves, it will be doubly hard."
Lynch opened the scoring on Saturday with a cool finish from the edge of the box on 37 minutes.
Elding had a couple of chances to increase his tally this season before that, but fluffed his lines in front of goal, while the excellent Mark McNulty pulled off a superb double stop to deny Aaron Greene and Raffaele Cretaro.
Sub Daryl Kavanagh helped Cork remain competitive in the second half, but Elding made sure of the win from the spot with seven minutes left, after defender Evan McMillan was fouled trying to get on the end of Lynch's free-kick.
Baraclough added: "Their 'keeper pulled off three of four excellent saves so it could have been more. But I don't think we dominated for a sustained period really. They were organised, full of energy and closed us down well.
"They made it hard for us, but they didn't really cause us a great deal of panic, only what we created with a sloppy pass or by taking the wrong decision.
"I don't think the conditions helped. It was very windy. But our decision-making could be better and we made it hard for ourselves again. Credit the lads, we found a way to win it."
