Ramsay,22, has trialled with United for a week and impressed enough to be offered a contract by Rini Coolen's Reds, report O Kosmos columnists Tony and Xanthie Rallis.

It's believed the Hindmarsh club see the athletic attacking midfielder as a potential replacement for left-sided attacking defender Scott Jamieson who left to join Sydney FC.

Ramsay left Australia as a teenager to play for Gretna in Scotland. He played youth and reserve team at Raydale Park but never made the first team and returned to Australia in 2008. 

He then joined Sydney Olympic in the NSW Premier League before being scouted for the sky blue youth team. He made one appearance for Vitezslav Lavicka's first team last season against Victory in the 2-1 major semi final loss at Etihad, coming on as a final minute substitute.

Meanwhile, former Bolton Wanderers youth player and Young Socceroo Aaron Mooy is back in Australia and keeping in shape with Sydney FC. It is believed he has three invitations to trial in Scotland, Italy and Holland.

Mooy, a talented attacking midfielder came to prominence after his performance for the Young Socceroos last year.

After leaving Bolton last season, Mooy reportedly panned youth development in England as being too results oriented.

"Over there [in Holland] everyone passes the ball around, it's not like everything's about results like in England," he said. "They try to teach the youngsters how to play.

"In England it's more, it doesn't matter how you play as long as you get the results."
