Arsene Wenger: "You could say that [I am surprised] if you look purely at the number of points they have. They were not expected there.

"They have bought very well in a very efficient way. Some players have made a name now who were completely unknown at the start of the season.

"Therefore when you look at their quality it is not surprising they are where they are.

"We knew Demba Ba and Papiss Cisse of course. We looked at them both.

"You cannot go for all the players who are good that are on the market.

"Newcastle lost Andy Carroll last year and they were searching for a striker, so credit to them [for signing Ba and Cisse].

"Also Yohan Cabaye and Hatem Ben Arfa are good business for them. That's why they are where they are.

"They are a team everyone knows will give you a big game, but what is important is our own performance."
