Theo Walcott today boasted that Arsenal have Europe running scared after their stunning 5-2 demolition of Fenerbahce.

The Gunners took control of Champions League Group G last night with an inspired display to silence the intimidating crowd at the Sukru Saracoglu Stadium.

Last season's quarter-finalists Fenerbahce had not lost at home in European competition for 15 matches but goals from Emmanuel Adebayor, Walcott, Abou Diaby, Alex Song and Aaron Ramsey saw the visitors shatter that proud record.

And Walcott believes the emphatic nature of last night's victory will make other sides sit up and take notice.

"All the teams in Europe will look and see the 5-2 win by Arsenal, away and with a young team, and I think they will be scared to play us," said the 19-year-old winger.

"That's the impression we want to give out to all the other teams. We do that and we have always got them on the back foot and hopefully we can just keep performing like that.

"It was absolutely brilliant. The main thing was getting the three points and everyone got their jobs right today. We scored five goals and it was nice to see us taking our chances.

"We knew their fans would be right behind them. But we quietened them down straight away by scoring two very early goals it was a brilliant performance."

But despite the one-sided scoreline, Walcott warned his team-mates there is still room for improvement, saying: "We will have to study this game ahead of the next one. We just need to take the positives out of last night because it's something we need to learn from.

"There were quite a few negatives as well but it's not going to always be perfect every game. Everybody wants to keep a clean sheet. But it was definitely perfect in the final third."

With Dinamo Kiev beating Porto 1-0 in Portugal, Arsene Wenger's side lead Group G by two points and victory in the return fixture against Fenerbahce in a fortnight will all but confirm their place in the knockout stages.

"It definitely does help [to qualify early] because the Premier League is important as well," he added.

"We are just looking at every game as it comes, not getting ahead of ourselves and that's all we can do really."
