MELBOURNE is still trying to secure further draft selections in this week's trade period, although any further deals the club is in involved in probably won't occur until Thursday or Friday.

Club list manager Tim Harrington said the Demons were pleased to already have four picks in the top 18 of next month's NAB AFL Draft, but gaining more would be sweeter again.

"[We're] trying to improve our picking position, really," he told afl.com.au on Tuesday.

"We've got 1, 2, 11 and 18, which are great picks, and the others at the moment at picks 34 and 50, so we're just trying to wind those down as best we can.

"It'll be the bigger deals that actually go first and then ours later on."

After trading midfielder Brock McLean to Carlton for pick No.11 on Monday, Harrington said Melbourne was unlikely to be involved in another trade of that profile.

"I would think now that the Brock deal is done, we won't have a whole lot of play in trade week," he said.

"But that's what we're doing – ringing [clubs] and getting on the front foot and just finding out what's happening out there, so that we might improve the position of the club.

"That's what I'm working on in the next couple of days."
