North London meets East London as Arsenal host West Ham at the Emirates Stadium in the Premier League.
Arsenal responded well to their devastating elimination in the Europa League at the hands of Olympiakos by putting in a professional performance in a 2-0 win against Portsmouth at Fratton Park to progress in the FA Cup.
The Gunners come into this game on a seven match unbeaten run in the league, including back-to-back home wins against Newcastle and Everton.
This tie is crucial for Arsenal, as a win would put them level on points with their bitter rivals Tottenham. An added incentive is that this would also leave the Gunners two points off fifth place.
West Ham, somehow with the talent of their squad, they are in a relegation scrap.
But, impressive showings against Manchester City and Liverpool, plus a solid 3-1 win against Southampton last week, shows that this Hammers side does have the quality to stay up.
West Ham’s last away win at Arsenal was in August 2015, so the Hammers will look to use this new found momentum to stun the hosts.
Here are the key battles that we think will determine the outcome of the game.
