West Ham midfielder Robert Snodgrass says they're capable of upsetting Chelsea this weekend.
West Ham beat the Blues 1-0 last December, a result that triggered a run of one defeat in nine matches and took the club clear of danger.
He said: “The important thing was to get that win as it gives us the confidence to beat Chelsea.
"When you get the confidence from winning away, you need to take it to your home stadium and win there, too."
The Hammers host Chelsea before Manchester United come to town six days later. Brighton, rivals Tottenham and Leicester City are all lined up before the end of October.
