Hoffenheim chief Alexander Rosen insists Roberto Firmino will only leave for big money.
The Brazil international attacker is interesting Manchester United, Liverpool, Chelsea, Arsenal and Borussia Dortmund.
"One thing is clear: if a club comes, then we are talking about a very high market value," said Rosen.
"We are aware that while he is a player of Hoffenheim, we will certainly not be the last stop in his career. But at this time I'm not worried.
"He feels happy, and we are glad we have him."
