Melbourne Heart chief executive Scott Munn has refused to guarantee coach John Aloisi will see out the A-League season.

Ten rounds into the current campaign, the Heart are still searching for their first win after going down 2-1 to Sydney FC on Sunday to heap more pressure on the coach.

Asked if he could guarantee Aloisi would remain coach for the rest of the season, Munn said the 37-year-old mentor would come under scrutiny.

“I don’t think I’m in a position where I can come out and make any of those statements,” he told Fox Sports on Monday.

“For us we will continue to work with everyone in the club and continue to analyse each position just as we do mine and the board looks at everyone.

“John is absolutely focused on achieving and that’s what our goal is as well.”

The Heart created a glut of chances in Sunday’s game and had come into the match looking to build on a dramatic 3-3 draw with Adelaide and an impressive 1-1 result against the reigning premiers Western Sydney last week.

But Munn said the gutsy performances count for nothing, with the Heart rooted to the bottom of the table.

“We’re not happy with the results,” he said.

“The admirable draws, the near losses, they’re not acceptable. We’re in a results game.

“John knows that we’re looking for results and the entire club do.”

Sunday’s defeat was the sixth loss this campaign for the Heart, who continued their woeful record on the road having not won outside Victoria since December 2011.

Munn said he understands the increasing frustration of fans who are calling for Aloisi’s head but insists the club would not act in a rash manner.

“I can tell you as a person who loves the club and attends every game I want to win every game,” he said.

“So that pain they feel, I feel.

“There are a lot of clubs in this league who are quick to fire coaches and that’s not what we do. We’ll continue to give John every support to achieve.”

Munn defended under-fire skipper Harry Kewell, who’s horrendous penalty miss on Sunday had fans and players alike in disbelief.

“Harry’s been an absolute professional and he was devastated after the game,” he said.

“But I think it shows the athlete that he is that he missed that penalty and continued at the level he did.”
