Olympiacos defender Omar Elabdellaoui is optimistic about the Uefa Champions League opener.
"We are ready for a big fight. We should not lose our concentration, work hard on defense and make them understand that it's not an easy game. We can have a positive result. If you don't believe then you've lost the game already. Bayern is a big team and has many good players. We have to remain focused" the 23-year-old defender said.
