PARIS, Aug 24 (Reuters) - A coolly taken penalty by Argentine striker Fernando Cavenaghi after just five minutes helped Girondins Bordeaux to a 2-0 win against Nantes in Ligue 1 on Sunday. A fluid-looking Bordeaux dominated the first half but struggled to add to Cavenaghi's penalty despite creating several chances and Nantes fought back after the break. It was not until four minutes from the end that Bordeaux sealed their win when Brazilian midfielder Fernando flicked in a corner to leave coach Laurent Blanc smiling after last week's loss in Paris. 'We had a really good first 25 minutes with six or seven chances and we opened the scoring, which was the most difficult thing,' Blanc said. 'We had a bit of trouble scoring the second goal which would have maybe allowed us to play a better match but you have to pay tribute to Nantes who didn't shut the game down and kept playing,' he said. Stade Rennes snatched a last-gasp 2-1 victory over Lille with two goals in stoppage time when they looked to be heading for defeat. Lille led after a 34th minute strike by midfielder Yohan Cabaye and both keepers had been called upon to make important saves. But a free kick from Rennes midfielder Bruno Cheyrou after 91 minutes was deflected in by Lille defender Emerson and that was followed three minutes later by a scrambled winner from striker Moussa Sow to complete a dramatic turnaround. Auxerre was left to rue a missed penalty as they went down 1-0 at home to Nice after a goal from Alaeddine Yahia. At the end of the third round of matches, seven-times champions Olympique Lyon and Olympique Marseille both have seven points after wins on Saturday, with free-scoring Marseille ahead on goals.
