"I'm delighted to be signing for Reading and excited to be joining a team that is going to be looking for promotion next season," Bridge told the club's official website.

"And, from the outside, Reading look like a team who are capable of getting back into the Premier League, a team that works hard for each other. That is something I want to be a part of and I'm really looking forward to next season."
The 32-year-old joins Reading having amassed a wealth of experience both in domestic, European and international football and director of football Nick Hammond believes that this experience will benefit the club.
"I'm delighted to have secured this agreement so early in the summer window," he enthused. "Both Wayne and his representatives have been very straightforward and professional to deal with and the player will add great experience and quality to our squad."
