Arsenal boss Arsene Wenger admits their defeat at Chelsea was a "big setback" to their Premiership hopes.

"It is a big setback for us," admitted Wenger, whose side travel to Manchester United next month. "I believe we have the strength, but at the moment we are six points behind Manchester United.

"When you add the four games we drew and today's loss, now we just have to come back and win games before we dream of the title."
