Saturday’s scoreless draw, coupled with second-placed Linfield’s 5-0 victory over Dungannon Swifts on Friday, puts the east Antrim side on 73 points with Linfield on 68.
Speaking to Larne’s media director Ian Cahoon, manager Tiernan Lynch said: “We’re frustrated we didn’t take all three points, but it was a great performance. I thought we played some really good football. We got the ball in good areas and worked the goalkeeper, who I think ended up getting man of the match.
"I can’t be critical of anything the players did. It’s just disappointing we didn’t get the ball over the line. They’re disapponted boys in there. They want to win every game, but that’s football.
"Our only concentration was Coleraine today, regardless of numbers or people round you. Our only concentrartion now is Ballymena in the Irish Cup on Friday (7.45pm) and that’s where it starts and that’s where it ends.
"We’ve to make sure that we take care of our end. We know it’s going to be difficult. This is a one-off game and winner takes all.”
