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."

Babbel also counts Patrick Ziegler as virtually a new signing, after injuries kept him sidelined for most of the last campaign with only six games to his name.

The German - whose father was born in Australia - is said to be close to full fitness again and set to shine next season according to his coach.

"The season starts in October and he will be 100 percent," said the German coach. "Very happy that he is this good condition."

Lopar is expected to slot straight into the number one role for WSW with regular keeper Vedran Janjetovic ruled out with a long-term injury which will see him out of action for three to six months, after an erratic season last campaign.

"For me it was clear that okay, we will have some changes," admitted Babbel after his side's disappointing title tilt.

"We have to do something. I'm very happy with the players."

The Wanderers are now targeting Leeds United who just missed out on promotion to the Premier League from the Championship last season after a disappointing end to their season saw them slip up in the play-offs.

Forward Mitchell Duke was relishing being back on the training field with a big game at their new home ahead of him.

"It's good," he said this morning. "There's quite a few fresh faces, which is always quite good to see. You can tell everyone's hungry to get straight back into it.

"There's so much look forward to in that game. It's going to be our first game in the new stadium. It's against a strong opposition who's a massive club in England who's got a lot of history,

"It's going be a massive test for us and it's always nice to test yourself against teams and players like that, to see where you're at and see what you need to get to before the season starts."
