Moving Heffernan from his usual full-back position to play alongside skipper Simon Colosimo is one option coach John van 't Schip is considering for Saturday's game, having used Matt Thompson as a stop-gap solution when Hamill was injured early in last week's match.

While the coach described Thompson's performance last week as 'okay' , he is thinking of either moving Heffernan or playing Josip Skoko in a more defensive position in a bid to cover the absence of Hamill and Beauchamp.

"There are options that we have tried out in training this week, so we will make a decision about that tomorrow," van 't Schip said.

"One of the options is to have Dean Heffernan play in the centre of defence with Aziz (Behich) as a left full-back.

"It's a possibility that we can play Josip from the back, just in front of the defensive four, but also coming in to get the ball, so we have a few options that we've tried out, and we will see what we do."

Van 't Schip feels that Brisbane's mobility in the midfield could prove an issue and sees strong defensive organisation as key to the Heart's hopes of registering back-to-back wins for the first time.

"Reinaldo is good with the ball at his feet, they have (Thomas) Broich making a very good impression, a very mobile midfield and a lot of players who ask for the ball running around the park so we have to be very organised and switched on," he said.

Van 't Schip said that seven matches into the season, things are finally starting to gel with his new team with last week's win over the Phoenix their best performance of the season so far.

"During the game, you could see the team was gelling more together and in some parts of the game, it looked very good, also defensively, as that is the main thing you think about with the balance of your team," he said.

One of the keys to the team's improvement last week was the performance of Gerald Sibon, who stepped into the Number 10 role behind the strikers and created plenty both in defence and attack for Melbourne.

The coach knows that the giant Dutchman's consistency is crucial in getting Heart playing the best football they can week-in, week-out.

"I think Gerald did a lot of work defensively, intercepting a lot of balls, although the most important was the one which set up the goal," he said.

"But also with the first goal, it was created in the midfield by him, together with Alex, which was very positive."
