Arsenal manager Arsene Wenger is pleased with how things are turning in his club's favour, particularly in the English Premier League table where the Gunners are enjoying a five-point advantage over second-placed Chelsea.

The North London team has recently defeated Liverpool on Saturday in the Premier League, and Wenger utilised the moment of joy to crack-up a humorous statement.

"After the Aston Villa game, if I had told you that [this would happen] I would have to run away because you would have killed me," Wenger told arsenal.com.

"It shows you that things can change quickly but that should as well alert us that it can go the other way."

Santi Cazorla provided the first goal on the 19th minute with a right-footed strike inside the box from a rebound, after his own header hit the woodwork.

Aaron Ramsey followed up in the second-half with a fantastic effort, just outside the box that saw the ball twirling towards the back of the net.

However, the French boss reiterated that his squad must keep themselves level-headed despite the short-term success enjoyed by Arsenal.

"We must keep good focus, continue to develop our team as there's room for improvement."

"At the moment, with 10 games played, you can say 25 per cent of the season [has gone]. You see the first tendencies and trends but it's still not settled."

"By the end of November you will have a clearer idea."

His team will be facing a Borussia Dormund squad in the UEFA Champions League that has recovered from an opening night defeat, thrashing Olympique de Marseille, 3-0, while winning their recent game at the expense of the Gunners.

Wenger revealed the importance of having a healthy team, in a holistic aspect, which played five difficult games in a span of about 15 days.

"It's very, very important now to continue our run and respond well against Dortmund because everybody will look at that game."

"It's a big game but let's recover first and afterwards I'm sure the team will go there with a great desire."
