Spilled one for Podolski's goal and could have given up a strange one shortly after that when he misread a back-pass.
Was unsure whether to drop off or track when Arsenal's fluid front four interchanged positions.
Put in a good cross at the end of the first half for Long but could not track Cazorla as the Spaniard drifted around.
Matched Giroud well but looked uncomfortable stepping up to deal with Arsenal's other threats. Lucky not to have conceded a penalty on Oxlade-Chamberlain.

Strode forward with pace every time the opportunity allowed and put across some inviting crosses.
Laid off for Livermore to strike the post and was energetic in the midfield channels on the right.
Did not have the energy or pace to prevent Arsenal's midfield number passing him to make chances.
Hull's best player on the day, he played some fine forward passes as well as striking the post with a tidy drive.
One half-chance in the first half when he headed over but too often found himself up blind alleys.
Missed some very presentable chances in the first half before being replaced.
Forced an early save from Szczesny but had limited involvement in front of goal.
Made a good first-half save from Jelavic and was solid in his handling under a succession of Hull crosses.
Did not often get forward but had the measure of Boyd on the right, making some important interceptions.
A mixed bag from the Spaniard, who suffered some lapses in concentration but was involved well for the third goal.
As usual, he was the man to set Arsenal going from deep and made some good interceptions too.
Lost Jelavic for Hull's only real chance but was able to mop up with some clearances thereafter.
Drifted from his right-wing station to cause Hull a whole lot of trouble. His was a quite brilliant assist for Ramsey's first.
If only he had been fit all season, how different Arsenal's fortunes might have been. Imperious and involved in all three goals.
A welcome return to fitness for the Germany playmaker, who linked up with his team-mates in some neat exchanges. Was also involved plenty in the goals.
Had to be brave in a number of bruising central midfield encounters but was lucky that his foul leading up to Arsenal's second was not punished.
Scorer of two goals in a lively performance. His first was a rasping finish, his second a real poacher's effort.
Missed one bizarre chance after a Harper mistake and led the line well. Great cross in the run-up to Podolski's first.
