Former Chelsea and Bayer Leverkusen midfielder Michael Ballack has urged Kai Havertz to remain in Germany amid interest from the Premier League.
The 20-year-old has supposedly caught the attention of both Manchester United and Liverpool following another impressive campaign for Leverkusen.
Indeed, Havertz has registered 12 goals and eight assists across all competitions this term, and Ballack believes that the midfielder should stay put at Leverkusen in order to become a better player.
Speaking to SportBild, Ballack said: "Players with his quality are in demand everywhere. But I think he's in good hands in Leverkusen.
"The conditions there are perfect for young top players and their development. Bayer play attractive football and their training facilities are very good.
"Leverkusen also offer a cautious environment, and as a player you can make mistakes without being the focus of criticism. You should appreciate that.
"Of course a player like Kai Havertz has to play in the Champions League, so it would be important for Leverkusen to qualify for it."
In what was Leverkusen's first Bundesliga game since the coronavirus shutdown, Havertz netted twice as Peter Bosz's men swept aside a struggling Werder Bremen 4-1 on Monday evening.
