Where the game will be won and lost on the field.
In what is believed by many to be the biggest game of the Premier League weekend Arsenal host London rivals Chelsea at the Emirates Stadium.
The two teams are among the title contenders and a win for either side in this clash will send the victors above Liverpool and to the top of the table.
There are some stars showing great form for both sides and here are the three key battles that fanatix thinks will be interesting to watch in the tie.
Olivier Giroud v John Terry
It’s likely to be a physical battle in the Blues box as these two tough players go up against each other.
With Theo Walcott likely to return to the Gunners side and Terry and Gary Cahill not possessing great amounts of pace, Giroud is set to push the defensive line back towards goal.
The Frenchman has seemed isolated at times when leading the line, but could get some real joy with the former England captain.
