The Reds came from behind to win 2-1.
Mohamed Salah scored twice and Milner told liverpoolfc.com: "It's so impressive, what he's been doing and keeps doing. We have to keep giving him them chances and hopefully he'll keep putting them away.
"He's been brilliant for us [but] it's all the boys up there as well, he couldn't do it without [them].
"Bobby does so much unselfish work and is getting his goals as well, Phil putting the balls through, Sadio as well.
"We're lucky to have such good players but hopefully with Mo he can keep providing the goods."
