The midfielder, who missed almost all of last season with injury, seems to be hitting his straps after a double in Wednesday's 4-1 win over Genk.
Speaking after the victory, Milner told BT Sport:"Everyone's delighted for him. It's the things that people don't see behind the scenes, the hard work around the training ground.
"He's got a great strike and he's good in those pockets. It's great to have him back and he's another option in that midfield, where there's already great competition for places."
