Antonio was impressive for victory at Southampton on Saturday.
"Obviously we showed in our performances in the last couple of weeks we've improved, but we haven't got the results we wanted," Antonio told West Ham's website.
"But we showed that we've got the fire, that we've got the grit.
"It was a massive result because we've got loads of respect for the manager.
"We started the season well before we went on a bit of a blip.
"I've been here for five years now and we've always come out of these blips. Hopefully this is the time where we can start moving forward and getting ourselves up the league."
