CARLTON legend Robert Walls fears his beloved club could lose “a generation of supporters” should the Blues fail to show promise and continue to lose in humiliating fashion.

The Blues’ 109-point loss to Melbourne on Sunday was their biggest under coach Brendon Bolton, as well as their biggest ever defeat at the hands of the Demons.

It means Carlton has won just two of its past 19 home and away games, following a dramatic fade-out during the back-half of its 2017 campaign.

Walls, a three-time premiership Carlton player and Blues premiership coach, said he attended Sunday’s game at the MCG as a spectator.

Besides the on-field disaster, Walls said the most concerning aspect of the day for the Blues was the array of young Carlton fans that left during the second half as the Dees ran away with the game.

“Melbourne kicked 15 goals to two in the second half. Where I sat, as every Melbourne goal went through in that second half, there’d be 20 Carlton supporters get up, grab their kids, put their thermos in the bag and go home, put their scarfs in their bags … you can’t blame them,” Walls told Fox Sports News’ AFL Tonight.

“They’re going to lose a generation of supporters.

“I hear on radio today one passionate Carlton supporter say he takes his three kids every week. He said his kids didn’t want to go (anymore). Kids want to have some wins, they want to feel good about themselves.

“I’ve got seven grandkids and one of them has swung to the Tigers — and I can’t blame her, because she wants to be on winners lists and see her team win.

“I’m really concerned about where they’re at because it’s been 23 years since they won a premiership.”

Walls added that there were only two numbers young Carlton supporters would want on their backs at the moment: No. 9 (Patrick Cripps) or No. 30 (Charlie Curnow).

“I heard Matty Lloyd say Essendon was not a great club anymore. Carlton’s not a great club anymore and hasn’t been for a long time,” Walls said.

Walls pointed out that 18 players on Carlton’s current list are ‘recycled’ players that have come from rival clubs, with only Lachie Plowman, Caleb Marchbank, Matthew Wright, Sam Docherty and Liam Jones receiving ticks from Walls.

But others, such as Aaron Mullett, Dale Thomas, Andrew Phillips, Matthew Kennedy, Alex Silvagni, Cameron O’Shea, Matthew Lobbe, Sam Kerridge and Jarrod Pickett, have been let-downs, according to Walls.

“This reset or rebuild, which the coach and Steve Silvagni the list manager have been working on for the last three seasons, I question them,” Walls said.

“They (recycled players) give their all, but everyone one of those players there … they’re original clubs were happy to see them go. Of that list there, there’s only one of them (Thomas) who came on big money. He’s been there for five years and I’d say it’s only this year where he’s really earnt his money.”

Walls also bemoaned the array of quality players, such as Bryce Gibbs, Eddie Betts, Sam Jacobs, Josh Kennedy and Zach Tuohy, that had left the Blues to join rival clubs.

“Carlton supporters come up to me and say ‘why isn’t Eddie Betts playing for us and why is Zach Tuohy down at Geelong?’ They are frustrated,” Walls said.
