Soccer/Rosenborg... 4 Bohemians... 0: To the recently arrived visitor it might look small and a little sleepy but the inhabitants of Trondheim make much of the fact that people have been coming from far afield to worship and learn in Norway's ancient capital. Emmet Malone reports from Trondheim

The won't have enjoyed the experience but if Bohemians came to town suffering from any delusions about the ground that still needs to be covered before they can compete seriously with the likes of Rosenborg on the European stage then they too left a little bit wiser last night.

In Dalymount Park last week Aage Hareide's side laid the foundations for their passage into the third round of these Champions League qualifiers while suggesting they were capable of adding to the single goal they scored had it been required of them.

Last night they delivered on the promise with an opening goal by Azar Karadas rounding off a first half in which Bohemians competed well and efforts from Harald Brattbakk, Roar Strand and Frode Johnsen following in a second during which they came close more than once to being completely overrun.

The inclusion of Strand, who was replaced before play had restarted in the aftermath of his 68th-minute goal, was the only change made by Hareide to the side that started in Dublin and the right-sided midfielder was the most persistent thorn in the visiting side's defence through the opening hour as he repeatedly slipped markers to create openings for those in front of him.

Bohemians never quite got to grips with the creativity he added to the home side's attacking play and by the time he departed midway through the second half they were already well beaten. Still they at least had some cause for pride with the bulk of their first-half performance, even if the achievement of generally matching their opponents was undone 90 seconds before the break by the sort of slack defending that Karadas had already shown a willingness to punish back in Dublin a week ago.

Once again the 20-year-old, who arrived at Rosenborg as a defender but has recently been used to add aerial power to the team's attack, scored with a close-range header, although this week's effort was even less of a challenge than last week's, with the goal following a cross from the right by Frode Johnsen to the far post where Karadas, entirely unmarked, nodded the ball home from a couple of yards.

It was a terrible blow for the visitors who, much as they had in the home leg, had competed well in almost every department, even if they once again failed to generate any real opportunities to grab the goal they needed if progress in the competition was really to be a possibility.

On the break they often looked threatening enough until they reached the final third of the pitch where, under some pressure from a very capable defence and perhaps suffering from a fear of being caught in possession, the Dubliners made a succession of poor choices and played far too many badly placed final balls.

Stephen Kenny had pinned his hopes on Glen Crowe making more of an impact this time than the striker had in Dublin but apart from an early half chance, when Espen Johnsen had been forced to smother the ball at the Irishman's feet, he again proved largely helpless as the game slipped away from the visitors.

Beside him, Robbie Doyle was once again erratic, striking a decent shot that forced a very rare save from Johnsen at one stage early on but also squandering possession more than once when players around him were in space, and failing, like both Mark Rutherford and Bobby Ryan, to exert any real pressure on Rosenborg's central defence with his occasional crosses.

It was after an attempted shot by Doyle that the local side broke forward to score their first goal immediately before the interval but it was also the former UCD striker who came close to scoring a consolation effort for the Irishmen 15 minutes from time. Stephen Caffrey found him in space on the right side of the box but his low shot flew just wide of the far post as Dave Morrison claimed he should have turned the ball back instead.

By then, however, the game had long been decided and Rosenborg were sure of a visit next week from Spanish side Deportivo La Coruna.

The first goal had clearly been a demoralising blow to a defence that had worked hard to contain the Norwegians, although the home support of 16,000 or so will have seen it merely as justice for the penalty their side had been deprived of by the match official only moments earlier, when Damien Lynch had, it seemed to just about everyone else in the stadium, taken Karadas's legs from under him inside the area.

After Brattbakk added a second six minutes into the second half, however, it briefly threatened to become a bit of a turkey shoot with Karadas and then Strand going very close to adding another goal.

The Bohemians back four, though, did well to steady themselves, although they looked constantly stretched in what remained of the game as the home side's midfield came to dominate completely.

Strand and Johnsen wrapped up the scoring with goals in the 68th and 76th minutes respectively, after which Shay Kelly made perhaps the best of several very good stops when he reacted swiftly to push Chister George's 15-yard effort around the post.

"We've said all along that we were unlucky to meet them at this stage of the competition but the reality is that we matched them for a match and a half," observed a defiantly upbeat Kenny afterwards.

"For 135 minutes there was nothing in it but in the second half tonight they beat us out the door. They played excellent football and were far too good for us. But better teams than us have been beaten here - Milan, Madrid, Borussia Dortmund. I can see why now."
