West Ham manager David Moyes told Sky Sports: "The performance was much improved in the second half. I feel we dropped two points in the end because of the chances we created.
"We did a good job in the second half. It was tough in the first.
"The biggest thing was to get a result on Thursday [in the Europa Conference League]. The performance wasn't where we wanted it to be so we wanted a performance today and overall I'm really pleased."
Aston Villa manager Unai Emery told Sky Sports: "We controlled the game better in the first half. We got to their box with good combinations but they attacked well with their wingers and we had to be careful of that.
"It was a good point, we prefer to win, but at the end it's fine.
"They had 12 corners and it's difficult to defend every corner."
