West Ham are third in the Premier League table at the moment, while winless Sunderland currently find themselves rock bottom.
The London outfit have the best away record in the Premier League this campaign, winning all three fixtures and only conceding one goal.
However, the Hammers have never won four consecutive away games in the same Premier League season.
Sunderland have failed to win any of their last 10 league games - the longest current run in the division.
