Marseille missed the chance to get themselves right back in contention for the European places as they were held to a goalless home draw by struggling Guingamp.The hosts, now without a league win at the Stade Velodrome since September 13, had their chances. Michy Batshuayi missed the target with an early header before Jonas Lossi produced a fine save to deny Javi Manquillo just before half-time.Shortly after the break Rolando saw a header hit the crossbar and Mauricio Isla wasted Marseille's last opportunity.Guingamp, who arrived in the south of France having lost their last five Ligue 1 games, could have stolen all the points late on but Steve Mandanda saved substitute Mevlut Erding's effort.
