West Ham boss David Moyes insists they'll test Arsenal on Sunday.
The Irons need a result to maintain distance from the bottom three.
Moyes said, "We will put out a team that will try and beat Arsenal. Last year, we challenged a lot of the so-called 'big teams' so we will try to give them a good game.
"They have got themselves in a great position [to possibly win the league.]
"They are very good. And they have a good record on the road. It makes it a difficult game but we have had a good couple of games against Arsenal over the past years and hopefully, we can do that again.
"I don't think we have many memories from the Newcastle game. In the main, we have done very well at home and hopefully we can do that and show what we are about."
