Antonio will miss Saturday’s trip to Liverpool with a hamstring problem after being forced off in discomfort in the last two matches against Tottenham and Manchester City.
“Micky is really positive about his injury,”Moyes said. “We’ve already got him on the bike and he’s moving, which for the type of injury we’re really pleased with.
“He had another scan and an ultrasound on Thursday as well. He’s in a good place. The big thing is that this is is certainly the fittest Micky Antonio has been [for me].
“There was a long period where Micky couldn’t play for 90 minutes, you’d have to take him off. So the big thing for me is that we keep Micky Antonio in that condition and when we get him back he’s ready to continue the performance he showed after lockdown.”
Antonio has been plagued by hamstring problems in the past but Moyes said the latest issue was “nowhere near” as bad as previous injuries and revealed the striker had altered his style of play.
“He’s much more aware of his body now, what he needs to do, his prep for games and his recovery work after them,” Moyes said.
“I think we’re hopefully going to get him back quite quickly. I think he has [changed his style]. His link-up play has become much better. I think he’s thinking more.
“But what we don’t want to change is his big strengths, his explosive speed and his power, because that’s why he’s been doing so well.
“I think he’s enjoying being a number nine, getting more goals. When you score goals it gives you more attention, it highlights you more, and I think Mick is enjoying that as well and he deserves it because he’s scoring goals for us.
“Seb [Haller] had lots of time to settle into Premier League football, to see whether he knows what it’s about,” added the Scot. “He’s got an opportunity to show what he can do and he’ll get that chance to do so.”
West Ham have taken eight points from the past four matches against Wolves, Leicester, Spurs and City and would complete a fine run by avoiding defeat at the home of the champions.
“I sense something different, I sense a different group of players, I sense a different feel around the club,” said Moyes.
“Obviously, we’ve got to hope we don’t get many injuries and stuff like that, but, overall, we can improve on where we were last year.
“I don’t think I have proved anyone wrong this time as I have just started. I always believed that I could do the job and given the right opportunity and right club I could do a really good job.
“First of all, you need to give the owners immense credit for, after having me and choosing not to take me, being big enough to come back and say ‘hey, you did a good job and we got it wrong’ and come back for me.”
