Melbourne great Garry Lyon states there are still doubts remaining over new Sydney Swans recruit Daniel Menzel when it comes to his defensive work.

Menzel, 27, became a Swan after the club picked him up as a delisted free agent as the forward failed to secure a new contract with Geelong.

Lyon toldย SEN Breakfastย he is concerned about the total net profit when it comes to Menzel.

โ€œItโ€™s not the two goals, itโ€™s the net result,โ€ Lyon said.

โ€œThe discussion about his defensive forward work stuff and the fact he doesnโ€™t tackle and put a lot of pressure on, results in goals the other way.

โ€œHe might be kicking two goals, but itโ€™s the net result that Geelong have looked at Iโ€™m sure and why other clubs werenโ€™t that keen.

โ€œIf he kicks 40, then I reckon he could also cost 40.โ€

Menzel has played just 73 games in six seasons for Geelong, due to needing four knee reconstructions, where he has kicked 136 goals for the Cats.

Former Essendon captain Tim Watson believes Menzel will find himself out of the team if he cant put out a defensive forward effort worthy of keeping him in the side.

โ€œGiven historically the way Sydney play, he wonโ€™t be in that team if he canโ€™t do what they want him to do,โ€ Watson said.

โ€œEven though theyโ€™ve recruited him and theyโ€™ve only given him a one-year deal, if he doesnโ€™t do what they want him to do, they just wonโ€™t play him.

โ€œAnd theyโ€™ve shown that in the past โ€“ you either step up or play the Sydney way or you donโ€™t play, they donโ€™t carry blokes who just play on the outside and donโ€™t participate in the defensive side of the game.โ€
