Walker reckons the combination of Albrighton's menacing deliveries and Downing's blistering pace has made Villa an exciting attacking force.
"I already thought Marc was a good working winger," he told AVTV. "I knew he could cross the ball with some quality but the quality even that he produces in training is frightening.
"He doesn't whip the ball in at pace, he just feeds it in, so it is perfect for strikers to get on the end of and hopefully he can set up a few more goals.
"Stewie is a very, very good player. I struggle to overlap him sometimes because he is that quick.
"He talks to me all the time, helps me out a lot and I really appreciate it."
