Caen moved up to second in Ligue 1 with a resounding 4-1 win at out-of-sorts Bordeaux.The visitors' evening got off to a great start when, with just five minutes played, Syam Ben Youssef pounced after Cedric Carrasso did well to parry Ronny Rodelin's volley.And the game was all but over when Caen netted twice in the space of five second-half minutes, with defender Damien Da Silva the unlikely scorer of both - the first a rebound from Andy Delort's free-kick and the second a header which crept in despite the best efforts of Bordeaux stopper Carrasso.Delort added a fourth with a deflected effort late on to rub salt into the hosts' wounds, before Andre Poko was dismissed for a second yellow card.There was still time for a Bordeaux consolation on 90 minutes as Enzo Crivelli netted following good work from Nicolas Maurice-Belay.
