LONDON - It was an all too familiar sight for Arsene Wenger as Arsenal threw away a lead to lose 2-1 at Swansea City on Sunday and the Frenchman acknowledged his flaky team are becoming a cause for concern.

It may only have been their second Premier League defeat of the season but Wenger's side have now lost nine points from a winning position, more than any other top-flight team, indicating it is a bigger problem than simply poor form.

After taking a second-half lead through Alexis Sanchez, Arsenal continued to push forward with 15 minutes to go and were punished by two goals in four minutes from Swansea.

The north London club's defensive frailties are not limited to domestic competition either. They squandered a three-goal lead to draw 3-3 at home to Anderlecht in the Champions League on Tuesday.

Ahead of the game in Wales, Wenger defended his back line against a host of critical voices including former Arsenal player-turned-pundit Paul Merson but the manager had no answers for the naivety of his team at the Liberty Stadium.

"It is difficult to explain how we lost the lead," Wenger told Sky Sports television.

"We were in control but they did not give up, we lost some decisive challenges in the middle of the park and paid for that. That is where we lost the battle.

"I worry that we concede the goals, yes. We just lost a game that we feel we should not have lost," added Wenger.

"You have to win the games you can win and today was one. If you want to challenge for the Premier League you have to be a bit more realistic."

Arsenal are sixth with 17 points from 11 matches, 12 adrift of leaders Chelsea and eight fewer than the total Wenger's side had at the same stage last season when they were top of the table.

The Gunners have mustered a worst start to a Premier League campaign once before, two seasons ago.

Germany defender Per Mertesacker said the team were over- complicating things.

"The game was completely in our hands but then we have to play serious football and not make mistakes," he explained. "We have potential but unless we play that serious football any team will punish us.

"We have to play simple. We think we can do some difficult things but we need to keep possession. After such a setback as Anderlecht we normally bounce back straight away but we didn't. We need to work hard on the issues now."

Wenger now has to contend with a two-week international break before the visit of Manchester United in the league on 22 November.
