Arsenal midfielder Alex Song admits their clash with Newcastle United will be crucial for their top four hopes.
The Gunners need victory to stay in fourth place.
Song said: "There is still all to play for and anything can happen.
"We have a big game against Newcastle, and we know they are also in the fight for fourth place.
"If we win that, and open up a bit more space between ourselves and the other challengers, then we will be in a good position."
