Three years after leaving Stamford Bridge for Benfica as a makeweight in the deal which saw David Luiz move in the opposite direction, chelseafc.com have announced that the Serbian has completed his return to the Blues.
Speaking to the official Chelsea website, Mourinho had this to say about Matic's return:
I am very pleased that Nemanja is returning to Chelsea. He has grown as a player in Portugal and has become a fantastic all-round midfielder. I am sure he will become a very important member of the squad and help us to achieve our ambitions.
While the midfielder told the same site:
I am very happy for this opportunity to be back at this club. I feel very good because of that and just want to say I will give my best to help the team and make the Chelsea fans happy
The fee that Chelsea have paid to bring Matic back is reported by the BBC to be around £21 million, far more than the £3 million he was valued at when he left Stamford Bridge in 2011.
