Nemanja Matic returns to the Chelsea team after serving a two-match ban in domestic football and Jose Mourinho admits the club has learned valuable lessons from the way he was allowed to leave for Benfica . Matic has become arguably the most important player in Mourinho 's team , providing the midfield security and physical presence which allows others the freedom to create . The Chelsea boss insisted he would 'never ' have allowed the Serb to leave Stamford Bridge but understands how it happened and applauded the board for showing the courage to sign him again for £22million , three years after he joined Benfica as a makeweight in a deal to sign David Luiz . Jose Mourinho believes Chelsea were 'brave ' in deciding to bring Nemanja Matic back to Stamford Bridge . Matic has become an important member of Chelsea 's first team since rejoining Chelsea . The 28-year-old has missed Chelsea 's last two games against Tottenham and West Ham due to suspension . 'Chelsea were brave by bringing him back , ' said Mourinho . 'If in this world you want to do the best for your club you do n't protect yourself from possible critics . You simply do what you think is the best . 'We wanted a midfield player and we had on the table three or four but the best one he was a former Chelsea player . I do n't say a player they lost but they were brave to say we are sure this is the right one , we are sure he is the best one , we are sure he is going to be a success here . 'Probably the next time Chelsea does a deal with a young player they will keep control . At these ages , the evolution of players can be good or bad . You can loan or even sell a player but you have ways of being in control of his future . 'Another aspect is the fact that Chelsea had so many managers in these years . It is difficult for the business people on the board . For one manager , Matic is the right profile of player , another one thinks Matic can go because I do n't like him . This guy I like because he is fast , this guy I do n't like because he is small . 'With a philosophy on the table , it is much easier for our board . If I was here , a left-footed player , 1.95 metres tall , would never , never , never leave . Never . ' Matic was handed a two-match suspension for pushing Burnley 's Ashley Barnes . Mourinho insists Matic would n't have been sold if he was in charge during the midfielder 's first Chelsea spell . Matic was sent off against Burnley last month for a retaliatory push on Ashley Barnes and missed the Capital One Cup final against Tottenham and a London derby at West Ham , when young centre-half Kurt Zouma deputised in midfield . He returns to the team for the Champions League last-16 tie against PSG at Stamford Bridge , which is poised at 1-1 after the first leg in France . 'It is goof to have him back with we did well without him , ' said Mourinho . 'So I 've told him maybe he is not so important . It was a bit of a joke and he laughed , but I told him we won a final and beat West Ham at West Ham , so we did well without him . 'But he is important , of course he is . He is very important in the balance of our team . Our team was developed with Matic in that position and everybody feels comfortable with him there . 'Zouma did amazingly well for us in those two games , in that position , but Zouma is a central defender and will always sbe a central defender , while Matic is Matic and the team feels very good with him . '
Nemanja Matic was used as makeweight in David Luiz 's move to Serbian international Matic . Chelsea rejoined Serbian international Matic from Benfica in January 2014 . Serbian international Matic boss Jose Mourinho said Matic was one of 'three or four ' options .
