Fernando Torres says Chelsea proved their title credentials after victory at Arsenal.

The Spain international fired the Blues ahead following some poor marking by Laurent Koscielny and Juan Mata's free-kick squirmed in to secure three points for the European champions after Gervinho had equalised on the stroke of half-time.

Torres said on Sky Sports 2: "We knew before the game it would be an important result.

"It was one of the main targets we have this season - winning these kind of games. We want to be in the top four for sure and fighting for the title.

"Today was the first big test. It's a very difficult stadium against a great team. It's very good for us."

Torres' goal was his fifth of the season and he acknowledged playing with a smile on his face was helping.

"I enjoy more this season," the former Liverpool forward said. "The kind of players I have behind me has given me a lot of support. I have to improve to create more and more chances for the team.

"I'm scoring more. The team still have a big way to improve. Not just me - everyone.

"I think we're showing as a team with this different style of football this season we're in the top. We can dream with a very good system again."
