Matthew Buck, who works for the PFA, has represented Milner since he was a teenager.
Buck told the 5Times podcast: “Left-back is a difficult one for him as he's naturally right footed. I wouldn't say he finds it easy but as people know from his personality and temperament he will always put the team first.
“James wants to contribute to the team and will sacrifice himself in order to give the team the best opportunity to win, It's a fluid system. He got a couple of assists against Burton as he got forward a lot and overlapped. It was the same at Tottenham.
“But you still have to have that discipline to fill in and cover defensively. He's learning all the time."
