Joe Ledley believes Aaron Ramsey 's presence in the Wales squad along with talisman Gareth Bale makes the rest of the players 'feel like God.'
The former Celtic ace has been full of praise for the Rangers playmaker ahead of a huge few months for his club and country.
Ramsey made a slow start to life in Glasgow after joining on-loan from Juventus in January.
But he has built up his fitness levels and could be key in Rangers run in as they compete for the Europa League, Scottish Cup and Premiership title.
The Welshman scored in an 84-minute cameo at Dens Park last Sunday which was his sixth Rangers appearance and just his first league start.
Wales face Austria tomorrow night looking to take a step closer to a first World Cup since 1958 with the loser facing Scotland in a friendly on Tuesday.
"They make everyone believe", Ledley told Sky Sports.
"For players in the dressing room, when they look left and see Ramsey and look right and see Bale, it makes you feel like God.
"If one is missing, the other one will step up. As a double act, there is nothing better."
Ledley maintains that the 31-year-old former Arsenal star can still contribute at the highest level thanks to his frightening fitness levels.
He added: "We have no worries with Aaron in terms of his fitness.
"And he's got more minutes under his belt now than he did for the last camp and scoring last weekend will have been great for his confidence.
"His fitness levels are frightening. I've worked with him for many years. He doesn't stop running. He helps out all over the pitch, tracking back.
"On the flip side he can also make that third man run and make the difference in the opposition box which then gets him his goals. He goes under the radar. He's still a massive player in this squad."
