Bayern Munich chief Karl-Heinz Rummenigge has warned Tottenham they risk losing Harry Kane.
The two clubs will face off in a fascinating blockbuster Champions League clash in North London on Tuesday.
"They have a good team," Rummenigge told reporters as Bayern prepared to fly to London on Monday.
"The question is whether they can keep this top team together for a long time, because Christian Eriksen's contract expires next year.
"There are certainly also clubs that are interested in Harry Kane."
He added: "Kane is a top player who, like Robert Lewandowski, scores an incredible number of goals.
"They are perhaps the two best strikers in the world right now.
"I hope Robert will do better than Kane tomorrow but it's not easy to stop him, he's a world-class striker."
