ARSENE WENGER hopes Arsenal's failure to make the most of their chances does not come back to haunt them in the return leg of the Champions League clash with Roma.

A first-half penalty from Robin van Persie gave the Gunners a slender advantage to take back to Italy in a fortnight's time.

However, the trip to the Stadio Olimpico - which will host the Champions League Final in May - should have been academic given the number of chances spurned by Nicklas Bendtner and Emmanuel Eboue.

Wenger said: I am happy with our performance, but of course there was room to score more goals.

"We know we need to attack over there. If we score once that should be enough."
