West Ham defender Vladimir Coufal feels they've raised their level after winning the Europa Conference League last season.
West Ham have kicked off the campaign in impressive form.
After winning the conference league we gained a lot of confidence," said Coufal to whufc.com.
Now we are playing like we feel bigger, with confidence, we trust each other, we trust our process, our football. We are keeping together. It is bringing the fruits and bringing the points, so we don't want to change anything.
"But, to be absolutely honest with you, I didn't expect ten points from these four games!"
