Royals fell to their fourth defeat in a row last Saturday as they lost 3-1 at Everton.
"As a team we still need to stick together," said the right-back.
"It's still close down there and when I signed (in January) we were six or seven points off and now there is only one.
"Against Aston Villa we have to make sure we win. All we can do is concentrate on ourselves.
"We have to do the best as we can and pick up as many points between now and the end of the season."
