The 27-year-old has put an end to months of speculation by putting pen to paper on a new deal with Italian giants Juventus.
McKennie’s old deal was set to expire at the end of the 2025-26 season, but he will now remain at Juventus until 2030.
"A player unlike any other, versatile and capable of occupying literally any position on the pitch – as demonstrated in recent months in which, starting as a midfielder, he has been able to express himself at a high level as a scorer, finisher, winger, full-back and even defender," Juventus said in a statement.
"A powerful tool that can be used on both the right and left flanks, available to Coach Spalletti to attack any opponent.
“A young man who has won the hearts of the fans and is now reaping the rewards of his daily work in training.
"Congratulations, Wes, from the entire Juventus family!"
