Bayern Munich are without winger Arjen Robben for their Champions League semi-final second leg against Real Madrid.
Robben suffered a leg injury eight minutes into Real's 2-1 win at the Allianz Arena last Wednesday, reports BBC.
Left-back David Alaba (thigh) and midfielder Javi Martinez (head) are both expected to return from injury.
Real Madrid right-back Dani Carvajal is likely to miss out with a hamstring injury, but Isco trained on Monday despite a shoulder injury.
