Edwards rates the Stoke City midfielder among the best in the world.
Allen, aged 27, has become an integral part of Stoke's midfield since signing from Liverpool last summer.
“I'd want to have Joe Allen in that midfield every day of the week," Edwards told the Mirror. “I think he's one of the best midfielders in Europe, I really do.
“I watch him train and he's something else. The way he can carry a team in the way he's done in previous games for Wales has shown he's become as integral to us as Gareth is."
