Andre Villas-Boas has said that Chelsea must reflect on their mistakes after losing 5-3 to Arsenal at Stamford Bridge this afternoon.

The Blues, who lost last weekend at Loftus Road, were expected to get back on track at home against Arsene Wenger's struggling Arsenal side. However, following a late brace from Robin van Persie, Chelsea were left without a point after succumbing to their second loss in a row.

"We've seen some great open games recently between the top teams and this is one more," the Blues boss told Sky Sports News.

"We will have to reflect on the mistakes we made and there are a couple of things we can improve, but the commitment and desire is there.

"We must evolve, it's a loss against a big team picking up form, it's two defeats in a row and we have to get things right."

Chelsea travel to Ewood Park next weekend to take on Blackburn Rovers.
