Last year's No.1 draft pick, Andrew McGrath is set to move into the Bombers' engine room in 2018.
McGrath, who spent the majority of the 2017 season in defence, told reporters on Monday he expects to play a pivotal role in new look midfield, particularly given the addition of Adam Saad, who will play off half-back.
"I played the last four or so games in the midfield last year, so I assume I'll move into the midfield development group and divisional group," McGrath said.
"I'll do a lot of my craft and skill work with the mids and whether I play there round one, I'm not really sure yet, but we'll see."
McGrath played 21 games for Essendon in his debut season, averaging 19.7 disposals, 2.8 tackles and 2.2 rebound 50s.
The 19-year-old returned to pre-season training today with the first to four year player, which included new Dons recruit, Adam Saad.
"Saady looked great on the track today. It's great having him run next to me, just feeding the handball off to him and letting him go," McGrath said.
