reporters Cardiff 0 Arsenal 3

Arsenal could have gone ahead as early as the second minute when Jack Wilshere turned on Ramsey's pass and clipped a shot against David Marshall's bar, and definitely should have gone ahead midway through the first half when Mesut Özil helped on a Ramsey pass to put Olivier Giroud clear on goal.
Astonishingly the striker found himself in so much space he stopped in anticipation of an offside flag, one which never came because the assistant referee had correctly judged Giroud to have been onside all the time. By the time Giroud realised he was free to play on it was too late as Steven Caulker had trotted back to cover. The Frenchman on the pitch looked annoyed with the linesman as if he felt a flag should have been raised, while the Frenchman in the technical area flapped his arms in frustration and looked to the heavens in despair.
Cardiff did create an opportunity to take the lead when Fraizer Campbell headed wide from Kévin Théophile-Catherine's cross, but the first half was mostly one-way traffic and there was a certain inevitability about the identity of the player who gave Arsenal the lead on the half hour. Ramsey had been cheered by the home fans at the start when his name was read out, and he was applauded again when he rose near the penalty spot to divert Özil's cross beyond Marshall with a perfect header.
Ramsey kept the celebrations to a minimum against his old club though he could probably have done a lap of honour and still been politely received. It was a goal of which Paul Scholes would have been proud and the Arsenal midfielder's 14th of what is turning out to be a prolific season. He had a chance for a second on the stroke of the interval, but took a fraction too long from Giroud's pass and ended up shooting too high.
Ramsey opened the second half by dribbling along the byline on the right and cutting back for Giroud to shoot, only to see Ben Turner block on the goalline. As if to prove he could be almost everywhere at once the Welshman then came close to repeating the trick on the left.
Cardiff's best chance of getting back into the game came when Kim Bo-kyung flicked on Andrew Taylor's cross from the left and Campbell got a downward header on target, forcing a smart save by Wojciech Szczesny low down to his right.
There was the merest hint of the crowd getting behind Cardiff when Théophile-Catherine brought another save from Szczesny with a long-range shot, though no sustained pressure from the home side. Arsenal always looked likelier to score, though as is their wont they produced plenty of slick approach work and few clearcut chances.
When Santi Cazorla did get a clear sight of goal from a Wilshere pass he lost his composure in all the excitement and managed only the most feeble of shots. Four minutes from time, just when it appeared the game would peter out quite tamely, substitute Mathieu Flamini regulation sleeves this time, though rolled up did rather better from Özil's threaded invitation by nipping into the area to whip a first-time shot past Marshall.
Theo Walcott came on at the end to help Ramsey to a simple second against a tired Cardiff defence, for a final scoreline that appeared to mock the difficulties both Manchester clubs have experienced on this ground this season.
