"I've made the cardinal sin of transferring out Mane for Salah," Bonfield says in the latest episode of the FPL Show. "The way that Mane's playing, he looks so deadly, so dangerous.
"He's been far more creative. That was something we levelled at him last season.
"OK, he's good for goals but not so creative. Well, he's matching Salah on the creativity stats, too."
Bonfield's wife, Sam, made the same switch last season but is not doing so this time around.
With Salah's 55 points only two behind Mane, she believes FPL managers should find room for both players ahead of a great run of fixtures.
"From Gameweek 13 the two of them together looks like a great idea," she says. "The double Liverpool attack looks really promising."
