The Mariners entertain Queensland Roar at Bluetongue Stadium on Saturday with the home side boosted by the return of attacking duo Dylan Macallister and Matt Simon.

Only Nigel Boogaard and Ahmad Elrich are unavailable for selection due to their respective injury concerns.

McKinna said: "If we can win two games of our remaining three we’d be a good chance of getting second spot and if we win all three we’ll be in there fighting for the Premiership.

"We still believe that we can win the Premiership and we won’t stop believing until it’s mathematically impossible.

"Our main goal is to qualify for the Finals Series and a win against Queensland will probably cement that, depending on other results, from then on in it’s a bonus if we can challenge for the Premiership."

Saturday’s meeting between the Mariners and the Roar at Bluetongue Stadium marks the seventeenth match up between the two sides in all competitions and not since their 2005 Pre-Season Cup triumph have the yellow and navy defeated their Brisbane-based rivals at Bluetongue.

Draws have overwhelmingly dominated past results between the two clubs, including six straight stalemates between October 2005 and October 2006.

McKinna said: "Queensland are similar to us in many ways in terms of their work rate and high tempo game and they’ve got a great midfield with Matt McKay and Massimo Murdocca.

"The last game that we played at Bluetongue Stadium was probably the best that we’ve done against them – Sergio Van Dijk scored a great free kick but after that Danny Vukovic didn’t have a save to make.

"We’ll go in to the game at the weekend full of confidence and thinking that we can get a result."
