We must improve at back - Fabregas

Arsenal captain Cesc Fabregas has warned his side can forget about winning the Champions League if their defending does not improve dramatically.

The Gunners left Liverpool with a point following an amazing 4-4 draw, where they had led in stoppage time through Andrey Arshavin's fourth goal of the night, before another costly mistake at the back allowed Yossi Benayoun to grab an equaliser.

"From an attacking point of view, we played one of the best games of the season. However, defensively we need to improve a lot if we want to be in the Champions League final," the Spaniard said.

"We have seen the best things we can do, but there are a lot of things we can improve on.

"We played in front of great players and great fans and the team has to be proud of what we achieved, but still we go home with the feeling we should have done more.

"We gave the goals away too easily and after all we did to create four opportunities to score four goals - it is difficult to take.

"It is the most difficult thing because when you attack you have the creativity to do what you feel.

"If defensively you are not well positioned, you will concede goals. We still need to do a lot of work on it."
