Spain:Steffen Iversen scored in the 31st and 58th minutes to give Rosenborg a 2-0 victory over Valencia in the Champions League on Tuesday, spoiling Ronald Koeman's debut as manager of the Spanish side.
The result at Mestalla Stadium improved Rosenborg, playing its first Champions League game under coach Trond Henriksen, to seven points and within one point of Group B leader Chelsea, while Valencia remained in last with three points, unlikely to reach the next round.
"It's a shame. It's now going to be much harder for us to advance. But in soccer, you can never give up," Valencia defender Ivan Helguera told Canal Plus TV.
Koeman, who left PSV Eindhoven to replace sacked Quique Sanchez Flores last week, witnessed his new team lose its third straight Champions League game.
The coach said he had not lost hope of reaching the next round.
"There's still time but the situation is pretty complicated," he said. "We started off controlling the game and then their first goal arrived and the problems began."
Henriksen said his side had been closer to 3-0 than Valencia was to scoring.
"In this match they didn't play well but Rosenborg came up with a great display," he added.
Rosenborg created the game's first chance in the 24th minute when Iversen's angled volley hit the post after Valencia goalkeeper Timo Hildebrand lost his footing.
Goalkeeper Lars Hirschfeld dived to parry Helguera's 29th-minute header, and Rosenborg responded with a swift counterattack to take the lead.
Swiveled to score
Marek Sapara charged down the field and, following an exchange of passes, sent the ball to striker Iversen, who swiveled to score off Hildebrand's right post.
Rosenborg almost doubled its lead but Yssouf Kone fluffed his header from Mikael Dorsin's hanging cross in the 33rd and then had his low shot blocked by Hildebrand nine minutes later.
Valencia's problems worsened in the 45th when Fernando Morientes, who had been injured by Bjorn Tore Kvarme early on, was carried off the field on the stretcher.
Vicente Rodriguez replaced Morientes at the start of the second half, but the Spanish team remained unable to slow Rosenborg's swift breaks.
Iversen doubled his tally in the 58th when he leapt to head Mikael Dorsin's corner from close range.
Koeman responded five minutes later by bringing on towering substitute Nikola Zigic to replace Joaquin Sanchez.
However, Rosenborg almost extended its lead in the 72nd when Kone hit the post from close range after Hildebrand parried Iversen's header.
The Valencia goalkeeper then denied Kone in injury time as Valencia supporters whistled their frustration at their team's display.
