Chelsea youngster Nathan Ake has joined Reading on loan until April 22.
The 20-year-old has made 11 appearances for Chelsea since joining in 2011 and has earned 13 caps for the Netherlands Under-21s.
"I am delighted to add a player of Nathan's quality to our first team squad at this important time of the season," manager Steve Clarke told Sky Sports News.
"He has been a fixture in Chelsea's first team squad this season and we are grateful that Chelsea have allowed him to join us here at Reading to get some competitive minutes on the pitch.
"He is a very talented player who I have been aware of for some time and I look forward to working with Nathan in the coming weeks."
Ake can play across the back four and in defensive midfield, and could make his debut in Reading's Championship match against Cardiff City on April 4.
