Berlin - Bayern Munich's Robert Lewandowski trained with a protective mask on Monday and could face Barcelona in Wednesday's Champions League semi-final despite a broken cheekbone, according to team-mate Jerome Boateng.
"He moved well and made a good impression, it looks like he's fit to play," Bayern defender Boateng told reporters in Munich after training with Lewandowski.
"He didn't have any fear, he is very brave and he will get used to the mask."

The 26-year-old Lewandowski, the German champions' top-scorer with 23 goals, sat out Bayern's 2-0 league defeat at Bayer Leverkusen on Saturday to try and get him fit for the first leg at the Camp Nou.
The striker broke his nose, cheekbone and suffered concussion during a clash with goalkeeper Mitchell Langerak late in Munich's German Cup semi-final defeat to Borussia Dortmund last Tuesday.
Bayern have said they will leave the decision to Lewandowski as to whether he plays, but the Poland international posted a picture of himself wearing the mask on Sunday with the text "Ready for the next challenge" in Polish.
