Bayern Munich's Franck Ribery has admitted his side were surprised by the ease with which they beat Arsenal but he has warned against complacency.
The German side defeated Arsenal 3-1 in the first leg of their Champions League tie on Tuesday night and they are now the hot favourites to progress to the quarter-finals when they renew rivalry on March 13.
Ribery had expected a big response from the Gunners following their shock FA Cup exit at the weekend, but Arsenal never threatened an upset and the Frenchman is confident Bayern can finish the job when Arsene Wenger's men visit the Allianz Arena.
"We didn't think it would be so easy. We know Arsenal are having some problems in the league, maybe they are lacking in confidence," Ribery is quoted as saying in The Sun.
"But we feel good and we're delighted to have got that result. We're all working hard together, with the will to play well, to win, to defend together. It's important to carry on like this.
"We will have to match that performance in the return leg. We're in good shape to reach the quarter-finals but nothing is ever over in football."
