It is Welsh star Bale who Holtby thinks England boss Roy Hodgson could do with most.
He said: "You see that in training, he's very confident, good on the ball and he's got one hell of a left foot.
"He's just a fantastic player. He's a hard worker, physically strong and just loves the game.
"He's keeps scoring for us and unfortunately he doesn't play for England, he would be great for England."
