PORT Adelaide draftees Sam Powell-Pepper and Joe Atley will be given every chance to make an immediate impact in the Power's midfield next year.

The Power were one of the big winners of Friday night's NAB AFL Draft with their haul of Powell-Pepper (No.18 overall), Atley (No.32 overall), gun forward Todd Marshall (No.16 overall) and promising midfielder Willem Drew (No.33 overall).

Power's general manager of football Chris Davies said that Powell-Pepper and Atley had the physical attributes to make the leap to the senior ranks next year.

"There's a couple guys there, certainly from a body perspective, that could come in and cope with the rigours of AFL footy straight away," Davies told reporters on Sunday.

"With four relatively early picks, we wanted to make sure that we were looking at the future, but also addressing needs as well.

"I'm sure we've got some guys who can help the club in the future."

The quartet will arrive in Adelaide on Sunday afternoon before training with their new teammates for the first time on Monday.

Marshall is a long-term prospect and fills the void in the forward line left by the departures of Jay Schulz and John Butcher.

"It's fair to say we've addressed one of the needs we thought we had," Davies said.

"We had to get a marking-type forward to the club and we've done that.

"From a body perspective, you'll see he probably needs a little bit of work.

"He's got some serious talent and he'll be able to compete for a long period of time for our club."

The club's newest additions will have to wait a week until they meet several of the Power's marquee names.

Captain Travis Boak, Robbie Gray, Chad Wingard, Ollie Wines, Paddy Ryder and Brad Ebert, along with Davies, coach Ken Hinkley and head of high performance Darren Burgess, left on Sunday for a four-day tour of Shanghai to promote next year's historic game against Gold Coast.

The players will meet students and Chinese business leaders while also taking their first look at Jiangwan Stadium, the venue for the round eight clash with the Suns on May 14.

"This is our first opportunity to go over with the AFL to have a look at what exactly exists over there at the moment," Davies said.

"It's a great opportunity to put some stakes in the ground and see what needs to be done over the next four or five months."

The Power won't be making a selection in Monday's pre-season draft.

Ugandan-born midfielder Emmanuel Irra, who plays for South Adelaide, will join the Power as a Category B rookie if he is overlooked in the pre-season and rookie drafts.
