The 21-year-old right back has established himself as a key player at club level for the Champions League winners.
Now he is looking to earn his place in the England starting lineup ahead of Euro 2020, which begins on Friday.
"When I was young I wasn't always a right back," James told reporters while on international duty, per Goal.com.
"So I've always supported the boys who played for the team I supported.
"[With Cole], we speak nearly every week. Probably one of the best left-backs to play the game.
"Even though he was a left-back the position is basically the same, just on the opposite side. He helps me a lot progressing."
