A one-year contract has been signed by Matic.
Three years after bringing him to Manchester United, Jose Mourinho signed him again, this time for another club.
The contract of Matic, a former Serbia international, expired earlier this month.
The enthusiasm he showed at the prospect of joining the project was very encouraging.
He said that Nemanja brings with him a lot of quality on the pitch and a focus and mentality that has consistently set him apart throughout his career.
During his time at United, Matic played in the FA Cup and Europa League finals.
He will be wearing the number 21 shirt for the winners of the Europa Conference League.
