Arsenal forward Theo Walcott has warned his teammates that they still have work to do if they are to qualify for the group stages of the Champions League.

The Gunners are huge favourites to advance from the qualifiers after an impressive 3-0 win over Fenerbahce in Istanbul on Wednesday night.

The Premier League outfit have a huge advantage after notching three away goals, but Walcott has demanded that his side do not get too carried away just yet.

"It felt like, with the tempo of game, we dominated it in the centre of park and if we kept on going at a high intensity we'd get a goal, and we did that," Walcott told reporters.

"It was three great goals and it's a great result going to the Emirates now on Tuesday night.

"Its nice and comfortable but we've got to be professional on Tuesday. They're going to want to come and make it up to the fans for tonight and we have to be ready for that."

Kieran Gibbs, Aaron Ramsey and Olivier Giroud scored the goals for Arsenal.
