The Sydney Swans go into Saturday evenings semi final clash with Adelaide knowing its crucial to their chances that they ramp up their defensive pressure.

The Swans were out tackled by the Giants in the shock loss to their home town rivals last weekend and have just one chance to make amends and keep their premiership chances alive.

Coach John Longmire (pictured) says while there’s a number of areas in which his side needs to improve, being more effective in the tackle is a priority.
