Richards believes Silva's help can get him another England chance.
He said: "Just playing with David is something special. He's a cut above the rest at the minute. Playing at right-back, he always gives me the licence to go forward. He always tries to play the ball to me.
"It's amazing to link up with that sort of player and long may it continue.
He's just inspirational and makes it all look so easy. He shows you how the game is supposed to be played."
