Liam Moore says the Royals can take nothing for granted when they visit Sheffield Wednesday on Saturday afternoon.
After a battling 2-2 draw against Sunderland last time out, the Royals' defender has said Wednesday will offer a different threat altogether.
Jos Luhukay's side sit in mid-table safety at the moment, with the play-offs out of reach, with Moore saying they'll be hoping to finish their season on a high.
"It's a dangerous place to go," he said. "Without any disrespect to them, they've got nothing to play for. When teams have got nothing really to play for, they play freely - take more chances - and it's dangerous.
"We've got to go there, learn from our mistakes earlier on in the season and try and beat them to make this Saturday a good one, and one where we can finally say we're pretty much safe as well.
"You look at the games we've got, two away and one at home, we're going to need to pick up, I think, one win and one draw.
"This is an important game. We need to be more attacking, we need to get shots off and we need to go out there and do whatever it takes to win the game. This Saturday is a good chance for us.
"We understand how big these three games are, not just for us but for the football club, this changes everything.
"We have to stay in this league and we'll do everything we can to do it!
"There's been belief all season but now it's time for action, no point in us believing we're good enough to stay in this league but we need to show it and prove it."
