The Ecuadorian defender took over from Michael Carrick as the Red Devils’ new skipper last season and Valencia has been earning plenty of praise for his strong performances under the Portuguese coach.
There had been some suggestions that Paul Pogba could be in line to take the armband from next term following his brilliant displays for France at this summer’s World Cup in Russia.
However, Mourinho has now explained his reasons for keeping Valencia as the Manchester United captain from next season.
Speaking at a news conference in Los Angeles, Mourinho said: “The captain was Valencia last season. I think he’s going to be the captain and when he doesn’t play, we have to make decisions.
“It depends on who is on the pitch, if Chris Smalling is, Ashely Young is, if Ander Herrera is or Juan Mata is, if they’re on the pitch they have an option.
“Nemanja Matic has all the attributes to be a Manchester United captain, but he arrived only one year ago.
“But I never cared much about the captaincy, I care more about the life in the dressing-room and the leaders. The armband means what it means.”
Mourinho has been tasked with steering Manchester United to a Premier League title challenge after their disappointing form last term left them without a trophy.
The Red Devils finished in second place in the Premier League table last season and without a trophy after they were beaten by Chelsea FC in the FA Cup final back in May.
Manchester United have not won the Premier League title since their famous final triumph under Sir Alex Ferguson back in 2013.
Mourinho led the Red Devils to the Europa League and League Cup titles in his first campaign at Old Trafford.
