With 12 clean sheets so far this season, West Ham have not conceded in 48% of their league games.
It is rather surprising to see a team from the bottom half of the Premier League top the clean sheet table after 25 games this term.
Yet, after their 2-0 win over Aston Villa at the weekend, that is exactly what West Ham have done.
With 12 clean sheets in the league so far, Big Sam's Hammers have registered one more than Arsenal and Chelsea - and two more than Spurs.
That means Sam Allardyce's side keep a clean sheet 48% of the time in the league - a very impressive statistic indeed.
It is even more impressive when you consider the fact that West Ham's squad has been decimated by injuries at the back this term, with the Hammers even playing without a recognised centre-back for 80 minutes against West Brom in January.
Of course, Allardyce's men have conceded more goals overall than the likes of Chelsea, Arsenal and Tottenham - but the margins are thinner than you may think.
Jose Mourinho's Blues lead the way, having let in just 20 all season, but West Ham's goals conceded column is only one more than Spurs - and three more than Liverpool.
With West Ham currently sitting in 15th, then, it is clear that their defensive form is not what is responsible for their mixed season so far. And in terms of clean sheets, Big Sam's side are currently the very best of the best.
