Denilson believes that Arsenal's victory over Dynamo Kyiv will give them "peace of mind" as they prepare for Sunday's Premier League clash at Chelsea.

It has been a difficult week at Emirates Stadium after successive defeats against Aston Villa and Manchester City and a change of captaincy following William Gallas' quotes in the French media. However Nicklas Bendtner's late winner - and a clean sheet - provided welcome relief in the Champions League.

Arsène Wenger described Tuesday night's result as the "first step" on Arsenal's road to recovery. Denilson agreed and admitted that it would give the players much-needed impetus ahead of their trip to Stamford Bridge.

"It was very important [to beat Kyiv]," said the Brazilian midfielder. "It's a victory that gives us peace of mind for the next match. We had difficult moments last week, losing the match, but now we've got a victory and that's all that matters.

"For sure it has been a complicated week, but we were very patient and the boss helped us a lot by talking to us about it. This gave us confidence and I think the squad is prepared. We are all conscious that we now have to improve in the Premier League."

Denilson lined up in midfield alongside the Club's new captain, Cesc Fabregas, on Tuesday night. He expects the Spaniard to flourish in his new role.

"He's a big player, the man who has the boss' trust," said Denilson. "He's only 21 but with a lot of experience and he is approved of as a captain.

"He did demonstrate some personality on the pitch and he was helped by Gallas, Silvestre and Almunia because it was his first time [as captain]. Everyone knows it's not easy but he had a great performance and showed some character."
