Last season's Champions League exit still grates with Arsène Wenger.

Arsenal were on the brink of the Semi-Finals last April after Theo Walcott's incredible 60-yard run set up Emmanuel Adebayor for a tap-in at Liverpool. With seven minutes of the second leg remaining the aggregate scores were locked at 3-3 but Arsenal were ahead on away goals.

Within seconds Arsenal's hopes were dashed when Kolo Toure was adjudged to have brought down Ryan Babel in the box and Steven Gerrard smashed home the resulting spot-kick. Babel's late fourth compounded the visitors' misery and, ahead of his team's latest Quarter-Final tie with Villarreal, Wenger reflected on a forgettable night.

"We were [the better team over the two legs]," insisted the Arsenal manager.

"I feel that we were guilty of not being focused when we scored the second goal [in the second leg] and we paid for that.

"We were a bit unlucky too because we should have got a blatant penalty on [Alex] Hleb in the first game [at Emirates Stadium] and there was no blatant penalty on Babel in the second leg."
