Jose Mourinho has said he is sad despite leading Manchester United past Middlesbrough for their fifth straight Premier League win on Saturday.
United came from behind to defeat Middlesbrough 2-1 but Mourinho did not enjoy the victory over his former assistant Aitor Karanka too much.
"It’s a very good feeling, as I was expecting I don’t feel the same happiness because my brother is on the other side," Mourinho told the BBC.
"Aitor Karanka did his job amazing away but my brother is sad so I'm sad.
"My players were phenomenal. We managed to do something I love – bring the fans to the pitch. The last 15 mins were 70,000 on the pitch against 11."
On why Zlatan Ibrahimovic's goal was disallowed, Mourinho added: "(Referee) Mr Mason is the one that knows that but he knows he made a mistake. I think it's sad because referees are sad when they make mistakes."
Despite bossing most of the game, United surprisingly went behind to a Grant Leadbitter goal.
But two late goals from Paul Pogba and Anthony Martial with less than 10 minutes left sealed the win for United.
