Liverpool boss Jurgen Klopp is ready to play Fabinho in central defence alongside Joel Matip if Dejan Lovren fails to recover from a hamstring injury.
Virgil van Dijk is suspended for the last-16 first-leg while Joe Gomez is sidelined with his recovery from a fractured leg.
Klopp said that Lovren is touch-and-go to make Tuesday’s match at Anfield.
‘Dejan, I actually have to wait minute by minute if there is a chance or not,’ Klopp said.
‘There will be a lot of moments where we have to defend. We have worked on that, we respect the quality of Bayern Munich a lot.
‘Speed, technique, experience, it is all what you need to be successful.’
Lovren has been out since January 7, when he went off after six minutes with a hamstring issue in the 2-1 FA Cup defeat by Wolves.
Klopp is also waiting to see if Xherdan Shaqiri is available after an abdominal strain.
‘Shaq did a lot, so it will be close, we have to see. Shaq had a clearing session yesterday and did very well. We have to see how he reacted.’
