Arsenal take on West Ham in the London derby hoping to keep their chances of winning the Premier League title alive.
The Gunners are currently 11 points behind league leaders Leicester City but have a game in hand and are still mathematically in the race.
West Ham meanwhile have ambitions of their own. The Hammers could still qualify for the Champions League but much like their London rivals they cannot afford to drop any more points.
Arsenal star Mesut Ozil is expected to start and will be the main danger man having provided 19 assists and setup an astonishing 119 chances.
On-loan Fenerbahce striker Emmanuel Emenike is available but is not expected to start for the Hammers tomorrow.
West Ham beat Arsenal last time around but have not done the double over the Gunners since 2006-07.
