Former North great David King believes Eagles recruit Tim Kelly will be the player who has the most impact at his new club.

After months of speculation, Kelly requested a move from Geelong back to Western Australia during the 2019 exchange period.

The star midfielder was traded for two first-round picks, picks 24 and 33, with a third-round pick and pick 52 coming back.

The 25-year old was coming off a huge season, averaging 25 disposals for the ladder-leading Cats and finishing fourth in the Brownlow.

And King believes he'll provide Adam Simpson's side with exactly what it needs.

โ€œI think the guy who is going to have the biggest impact on his new club is Tim Kelly,โ€ King told SEN Breakfast.

โ€œThereโ€™s no doubt about that in my mind. The Eagles have been the worst ground ball team in the competition the last two years in terms of winning the ball thatโ€™s spilling, thatโ€™s bobbling, whether it be off clearance or a general crumb.

โ€œThis is where Kelly is elite. This is where he can change the game and one man can make a massive difference.โ€

King compared the influence Kelly will have at West Coast with Patrick Dangerfield's at Geelong.

โ€œIf you think of what Patrick Dangerfield did for Geelong when he went there. They were the worst clearance team and 13th in contested footy, now theyโ€™re second and third,โ€ he said.

โ€œIn that one season, he took them to second and third and we have seen Lachie Neale do the same thing for Brisbane.

โ€œOne player, an absolute jet like Kelly is, going into an already functioning footy club and a gun midfield that score from stoppage, I think thatโ€™s the biggest (difference) in the competition in 2020.โ€
