GREATER Western Sydney coach Kevin Sheedy believes it is only a matter of time before Tom Scully is seen only as a Giant, suggesting his Melbourne past will be forgotten by fans.

Scully played his first game against his old club on Sunday afternoon, gathering 19 possessions in a 78-point-loss.

"Sooner or later it will be like Anthony Rocca (for Collingwood) on Anzac Day against Essendon, everybody forgets he was actually selected by Sydney," Sheedy said after the game.

Scully came under close attention from former teammates who physically pressured him on and off the ball all day.

"He's always going to have Melbourne play tight on him at least for the next year or two. Tom Scully is basically a first-year player and his 30 games playing at Melbourne before he came over to us wouldn't have been a hell of a lot," Sheedy said.

"He's learning and building up his body to get a bigger frame and all that sort of development that you do is probably going to come between 20 and 24.

"When he comes to his 50 to 100 games like a lot of the Melbourne boys have, he will only get better."

Scully was given a hostile reception from Melbourne fans, with most of the 20,070 crowd booing him every time he gathered the ball. A banner was confiscated early in the day and some fans sat close to the Giants bench to heckle the 21-year-old when he came from the ground.

Sheedy said he was confident the negative attention would affect the composed and steely midfielder.

"I told him to go out and enjoy the game and don't worry about it. Fans are missing him obviously but you can't be worried about what the fans say. They love the game and they'd love to see their club not lose good players," he said.

"What's wrong with a few boos and hisses? That happened all my life. Who cares? As a matter of fact you should really antagonise them just to make sure you do enjoy it."

The game was the Giants' first at the MCG, making it the 10th stadium they have played at in their 13 AFL games and Sheedy said the experience of playing at football's true home would be invaluable for his young squad.

"I think it was very important for us today that our players actually got to play on the MCG. That's a hell of a difference from Skoda Stadium where they played last week," he said.

"I think they'll understand the extra running and spreading from stoppages, just how super fit you've got to be when you're playing on a ground like the MCG."
