It's true that Chelsea has been running riot in their past matches this season. Nevertheless, West Ham should not be looked down on as they had always been a hard nut for the blues to crack.
West Ham has a formidable defense and a history on being a disturbance to Chelsea... But with the form and spirit in the blues, I think they'd crack West Ham who are at home advantage, but not without a scratch.
I predict 1:2 on their match today, because they have kept the record of playing under3.5 goals... But the match might as well end as 1:1
I recommend GG (both teams to score) for this match to stay on a safest side of bets
