Inter Milan began the defence of their crown by taking the lead and then coming from behind to draw 2-all at Dutch side FC Twente.
Lionel Messi netted two superb goals, had a penalty saved and twice rattled the woodwork as Barcelona romped to a 5-1 comeback victory over Greek champions Panathinaikos in Spain.
Tottenham Hotspur let a 2-goal lead slip in germany as they drew 2-all with Werder Bremen in their Champions League debut.
