Amid talk of a possible exit, the Portuguese manager decribed the reports as "garbage" and insisted his intention was to "bring the club to where the club belongs".
Mourinho is currently midway through the three-year deal he signed when he succeeded Louis van Gaal in May 2016, and is happy with the backing he has received from the Old Trafford club by going after his transfer targets and getting them.
Currently leading the chase for Arsenal star Alexis Sanchez, the Red Devils are second in the table this season, albeit 12 points behind leaders Manchester City. Last term, Mourinho won the Europa League, the League Cup and the Community Shield in his debut season, although they did finish sixth in the Premier League.
It is understood that talks between the United hierarchy and Jose Mourinho's agent Jorge Mendes began in October and, with the former Chelsea and Real Madrid manager's current deal expiring in June 2019, a new contract is reportedly on the table to tie him at the club until 2021.
