Manchester United's manager says Celtic will provide a stern test for European champions Manchester United despite their dismal away record in the competition.
Sir Alex Ferguson says the regional rivalry between the English and Scottish champions will ensure a pulsating Group E clash at Old Trafford.
United have a 16-match unbeaten home run in the competition while Celtic have lost 17 of their last 18 away games in the Champions League.
Ferguson saysScottish and English have the same mentality and both teams will have a go in what he predicts will be an open game.
Two years ago Celtic gave United a major fright at Old Trafford where they took the lead before going on to lose 3-2.
