Arsenal fullback Bacary Sagna says it's now all about Chelsea after their victory at Champions League rivals Partizan Belgrade.
Captain Cesc Fabregas and centre-half Thomas Vermaelen could return for Sunday's trip to the Barclays Premier League leaders where Sagna knows Arsenal's title credentials will again be under the spotlight.
"We had to win against Partizan because we did not play well at the weekend, conceding three goals," the France full-back said.
"Every game is a test because the season is long, where you have to play match after match.
"Now we need to stay focused and look forward to the next game, and we have to make something at Chelsea. We have to play our football.
"We know we have the quality to beat them.
"It will be an open game, but it will be about us, not them."
