AC Milan coach Massimiliano Allegri is confident in his team\'s UEFA Champions League chances despite being paired with Barcelona, who he described as the \"best team in the world.\" in the quarter-finals. Serie A leaders AC Milan played the Spanish champions in the group stages, drawing 2-2 away before going down 3-2 at home. It meant they finished second in the pool, but a wild 4-3 aggregate win over Arsenal in the last 16 means they face the defending champions again. \"We\'ve drawn the best in the world, but we can do well because we\'ve improved since the last time,\" he said. \"We played well defensively in Barcelona and then just as well in the home game, even though we lost. We have to believe in what we\'re doing and Milan always give their best in these games. \"We\'ll see if we can get some players back from injury, but we\'ve got to accept what happens,\" he added. \"It will be very difficult, but our self-confidence has grown a lot since those two games and we have the chance of going through. Let\'s look on the positive side, if we get through, we\'ll have a great chance of reaching the final.\"
