Stuttgart director of football Sven Mislintat has hinted Silas Wamangituka could be sold this summer.
Everton and Fulham have been linked with Wamangituka over the past couple of weeks, while reports over the weekend claiming AC Milan are also eyeing the 21-year-old.
Mislintat said, “If it's up to us, we want to keep the group together, that is clear. But if offers come, we would have to talk about them – also in the interests of the players.
“I'm not torn when it comes to this topic. I'm pleased that the players took such a step.
"The fact that some of them were able to move into focus (and become targets for other clubs)."
