Two superb goals by Alessandro Del Piero handed Juventus a 2-0 win at Real Madrid in the Champions League on Wednesday and a place in the knockout stage with two games to spare.
Holders Manchester United, former winners Bayern Munich and Ligue 1 champions Olympique Lyon moved a step closer to the last 16 but Arsenal still have work to do after a 0-0 home draw with Fenerbahce.
Del Piero inspired double European champions Juventus with a low left-footed drive from the edge of the penalty box in the 17th minute and sealed the win with a trademark free kick midway through the second half.
Del Piero was delighted to score in front of new Argentina coach Diego Maradona was in the crowd to watch the game.
"Maradona was in the stands? I am happy to have scored in front of him. I hope he comes to watch us more often," joked Del Piero. "I am proud of the applause I received at the Bernabeu, an incredible stadium and an extremely important one. You live for these kinds of emotions."
