Real Madrid left-back Marcelo insists his side will be treating APOEL with the utmost respect on Wednesday night, despite the Spanish giants having all but sealed their spot in the UEFA Champions League semi-finals.Los Merengues go into the quarter-final, second leg at the Bernabeu holding a 3-0 advantage following last week\'s contest in Cyprus, and it would be a huge surprise to see Jose Mourinho\'s men fail to make the last four.Nevertheless, Brazil international Marcelo is determined not to take unfancied APOEL - making their debut at this stage of the competition - lightly.\"Against APOEL, we must go out on to the pitch focused if we want to get through to the semi-finals,\" he warned.\"We will go into the game with respect and well aware that we are facing a team who, if they\'ve reached the quarter-finals, cannot be weak. We\'re going to try to repeat what we did in Nicosia because we want to get through.\"On Real\'s chances of lifting a record tenth European title, Marcelo added: \"Any player would want to win it and I\'m no different.\"But there are still three games left to reach the final and we know we have to continue doing well to win it. There\'s still some way to go and we must work very hard to be champions.\"
