The American defender arrived from Tottenham in 2016 and he has continued to impress at St James' Park.
After a slow start to the season he has helped the Magpies climb into the top 10 after making three appearances in the league.
He has worked on his technical side of the game under Benitez and the 24-year-old admits the Spaniard will continue to help him improve.
Yedlin told ESPN: "It's a very physical league. It's a league that if you lose focus for even a little bit of time, they can punish you.
"Working with Rafa has taken my game to another level."
