Leigertwood has joined the Royals from Championship leaders QPR and knows he will have to perform in order to hold down a regular place in Brian McDermott's competitive squad.
"I've settled in really well," he told the club's official website. "The manager, the players and the staff have all been really welcoming and I'm just looking forward to getting out there, getting my boots on and preparing for Saturday's game.
"I wanted to come to a club who were looking to push on, and I saw Reading as a perfect opportunity to do that. I've come here to play.
"I've come here as a midfielder but there's the option that I can play at the back too. Obviously I'd prefer to stay in one position, but if I'm needed to play anywhere else it's no problem.
"And I know there'll be competition for places - there always will be in a good squad like this. So I know I've got to perform."
