Arsene Wenger believes that Chelsea's brilliant start to the season is down to the high spirits they find themselves in after winning a string of games on the bounce.

The Frenchman believes that the Premier League title is well and truly out of sight after Chelsea took a 12-point lead, with Arsenal failing to take the initiative and stumbling to Swansea City yet again.

The Gunners took the lead through Alexis Sanchez early into the second half but found themselves on the losing side as the Welsh club came back to score two goals in quick succession and handed Arsenal their second loss of the season.

"There's no obvious reason. They had a good start and we have gone through that too. As long as we don't lose, you don't question yourself. There's a little bit extra spirit in the team that gets them through when it's tight," Wenger told www.Arsenal.com on Chelsea's brilliant start.

The north London club have been ravaged by a series of injuries to key players, especially in defence, with Laurent Koscielny and Mathieu Debuchy both out with long term injuries.

Nacho Monreal, who is primarily a left-back has been deployed at centre-back to cope for the lack of personnel, which has backfired on Wenger. Calum Chambers is at right-back but the defender was left stranded too often, allowing easy balls into the box, which led to the second goal.

"We play a lot, we give a lot. I believe that overall we controlled them quite well defensively but suddenly in the last 15 minutes you could see that we dropped and allowed them to be dangerous," Arsenal boss said.

"Having said that, the free-kick is difficult to predict that he would score from there. It's not like we gave a great goal chance away. I feel the free-kick was a bit harsh but he took it well and Swansea is a good team," the Frenchman added on Arsenal's leaky defence.
