Bayer Leverkusen coach Peter Bosz admits fans will have to wait to see new signing Timothy Fosu-Mensah.
The former Manchester United fullback joined Bayer this week.
Bosz said, "He has to be quarantined for five days after his transfer and is not yet allowed to train with the team.
"I spoke to him first, I'm not allowed to meet him personally yet.
"That's why I don't know how fit he is."
