They face Leeds United in their first game at their new home next month and today coach Markus Babbel put his new-look squad through its paces on the training ground for the first session of pre-season.

The club saw an incredible 14 players depart at the end of last season and while the rebuild has only just begun, Babbel has already brought in five new faces, including some key signings.

Babbel kicked off his rebuild with visa players including Polish midfielder Radosław Majewski, Swiss midfielder Pirmin Schwegler and fellow countryman keeper Daniel Lopar as well as former Jets fullback Daniel Georgievski.

The club also added fringe Socceroo Dylan McGowan last week, with his brother Ryan tipped to join rivals Sydney FC to add spice to the Sydney Derbies next season.

But not all were at today's training session, with some given an extended break after gruelling seasons overseas.

However Babbel expects to have all his signed players on the ground in Sydney 10 days before the Leeds clash at Bankwest Stadium on July 20...with the new faces likely to play at least 45 minutes.

Babbel says he's rejuvenated too after an off-season break saw him return to his native Germany to recharge his batteries.

"It was good, very important," he said at training this morning. "I saw all my family and friends and the weather was a bit better than it is here.

"I'm full of energy again. We start and I'm very hungry and really looking forward."
