Matic said he was "delighted" to be joining at "an exciting time".
The Serbia midfielder added: "To work with Jose Mourinho once again was an opportunity I couldn't turn down.
"I have enjoyed my time at Chelsea and would like to thank the club and the fans for their support. I cannot wait to meet my new team-mates and to start training with them."
