Masked Lewandowski starts against Barcelona

Bayern Munich's Polish forward Robert Lewandowski walks toward a ball during a training session at the camp nou stadium on May 5, 2015

Polish striker Robert Lewandowski starts up front for Bayern Munich in the first-leg of their Champions League semi-final away to Barcelona just a week after breaking nose and cheekbone. Lewandowski will play with a protective face mask after suffering the injuries and concussion in Bayern's German Cup defeat on penalties to his old side Borussia Dortmund last Wednesday. Former Barca boss Pep Guardiola also left Mario Goetze on the bench for the visitors with Thiago Alcantara also making his return to the Camp Nou in midfield alongside former Real Madrid favourite Xabi Alonso. Thiago will not face his brother Rafinha from the start at least as he is left on the Barcelona bench as Luis Enrique names his strongest available side. Lionel Messi is accompanied by Luis Suarez and Neymar in attack as they look to add to the 108 goals the South American trio have scored between them this season.
