Arsenal have won eight of their last nine home Premier League games against West Ham, losing the other game in that sequence 2-1 on the opening day of the 2015-16 campaign. Indeed, today's visitors have won just two of their last 23 league matches with Arsenal since a three game winning streak between February 2006 and April 2007.
West Ham ended a seven game winless league run with a much-needed 3-1 victory at home to Southampton last weekend. David Moyes' side remain in serious relegation trouble, however, as they sit level on points with 18th-placed Bournemouth with 10 games of the season to go.
