Here are the top five statistics ahead of Sunday's encounter:
10 - Arsenal have won ten and drawn two of their last 12 Premier League matches with West Ham, this includes a seven-match winning streak.
In each of the teams' last four domestic meetings, the Hammers have opened the scoring, only to see their London rivals come from behind to claim three points.
5 - Theo Walcott could make a surprise start for the Gunners, having been named on the bench in the club's Boxing Day victory over Queens Park Rangers.
The England international have scored an impressive five goals in his last four appearances against the Hammers, although he is yet to find the back of the net this season, having played just 21 minutes of league action.

3 - Unfortunately for Sam Allardyce, West Ham appear to leak goals when they face the Gunners - in each of the last 5 meetings the Hammers have conceded at least 3 goals.
To further compound matters, the visitors have only failed to score in one of their last 11 Premier League away matches. Expect goals!

50 - Alexis Sanchez is the key man for the Gunners in this tie. Having scored his side's opener, before assisting the second against QPR, the Chilean international has now directly contributed to 50% of Arsenal's league goals (10 goals & 6 assists).
He has scored a Premier League goal every 140.7 minutes, while creating 47 goal scoring chances for his teammates - the division's third best tally.

|Stewart Downing||West Ham||17||378.25||52|
Andy Carroll could pose a tremendous threat to Arsenal's lacklustre defence. He offers West Ham aplenty with his towering presence and an impeccable ability in the air.
This season the Englishman has won almost twice as many aerial duels, per match, as any other player, while scoring two (of three) goals with his head.
|Team||Aerial Duels Won per App||Headed Goals||Appearances|
|Andy Carroll||West Ham||9.88||2||8|
|Christian Benteke||Aston Villa||4.67||0||9|
