Andrea Pirlo has discussed West McKennie's weight loss at Juventus, insisting that the United States midfielder is "more professional than when he arrived".
McKennie joined Juve on an initial season-long loan from Schalke last summer, and impressed enough in the first half of the 2020-21 campaign to earn a permanent contract at the Allianz Stadium.
The Bianconeri invested €18.5 million (£16m/$23m) in the 22-year-old's talents, and he is now a key member of Pirlo's squad, but the Italian says he was a long way from the finished article after leaving Germany.
