Toner’s last Ireland appearance came in 2020 and he retired two years later after 16 years of service with Leinster.
While he admits he “doesn’t want a lot of rugby” since hanging up his boots, he still supports Ireland.
He believes Andy Farrell’s side are in a good place but believes “someone needs to nail down the line-out call”.
He says Tadhg Beirne is a “phenomenal player” but players being moved between the second row and the back row impacts a line-out specialist.
“Tadhg is a phenomenal player, but I don’t know if I would have him up there as one of the best callers in the game,” Toner said.
“But at the same time I don’t think anyone has stepped forward.
“There’s different roles and different positions. Because they are all interchangeable. It’s the same with Ryan Baird, who can play six.”
Toner added the talent coming through for Ireland in the second row is “huge”.
“Edwin Edogbo is there and Tom Ahern, if he can get a run of games, I think he is a very good line-out caller and he’s six foot nine.
“There’s a good few lads coming through, and it’s good to see Joe McCarthy coming back from injury because I think they missed him.”
