New Manchester United manager Jose Mourinho has said he has "a job everyone wants" but has admitted he is disappointed the club are not playing in the Champions League.
Mourinho was appointed as Louis van Gaal's successor in May and on Monday he officially started work at Old Trafford, before addressing the media on Tuesday.
He said at a news conference: "It's a job that everyone wants and not many had the chance to have ... and I have it."
United will not be competing in the Champions League -- a competition Mourinho has won twice -- in 2016-17 after the side finished fifth in the Premier League last season.

Mourinho said: "We have to make sure this club is where it has to be ... which is the Champions League."
The former Chelsea boss also appeared to take a swipe at Arsenal manager Arsene Wenger, with the pair having endured a fraught relationship in the past.
He said: "There are some managers the last time they won a title was 10 years ago. Some never have ... I did was a year ago."
United have already signed defender Eric Bailly from Villarreal and striker Zlatan Ibrahimovic, who was out of contract after his terms expired at Paris Saint-Germain.
The club are set to bring in attacking midfielder Henrikh Mkhitaryan from Borussia Dortmund and Mourinho then wants to add a further player to his squad to make clinch their "four priorities."
He said: "From this four, we have three... when we have the fourth I breathe."
Sources have told ESPN FC that United will persist with their attempts to bring France international Paul Pogba back to the club.
He also staunchly defended his policy on giving youth players a chance in the first team.
Reading out from a prepared statement, Mourinho said: "How many minutes do we have left ... I have not time to answer it. It would take 10 minutes to answer it.
"I knew this question was coming. Do you want to know how many players I have promoted from academies? Forty nine. Do you want me to list them out? I promoted 49 from the academies at clubs and two factors that are important for these records.
"Sometimes you have no other choice but to promote them because you have injured. That is one factor. The second is when you are not playing for big targets it is easier to bring them up, outside the pressure of the big moments.
"My record with injuries is very low -- even from the UEFA studies, there were many times the team with the least injuries in the whole of Europe was mine. Last year the only season of my only career that I was not fighting for the title -- every other season I was winning or finishing second, or finish third once but still fighting for the title.
"I still did 49 and some of them we are speaking about big names -- players that today are Champions League winners, playing for national teams. Forty nine is a lot. Once more -- it's one lie repeated many times. Sometimes it looks like it might be true but it is always true. Many of you ... the names. If you want them, I'll give them to you."
Mourinho was also asked about Ryan Giggs' decision to end his 29-year association with the club in order to pursue a career in management.
The Portuguese coach said of Giggs, who was Van Gaal's assistant: "As for Ryan: it's not my responsibility that Ryan is not in the club. The job Ryan wanted was the Manchester United manager.
"That's not my fault -- the owners and Mr Woodward wanted me. Ryan, for the moment, wants to be a manager. I decided years ago I wanted to be a manager.
"Many of us start as assistant coaches and a moment arrives to making a decision. Ryan could have been what he wanted -- any important job but he made a decision where you need to be brave."
Mourinho also suggested that United captain Wayne Rooney will not play in midfield for him next season.
Rooney, 30, had been used in a deeper midfield role for United and also England at Euro 2016 but, speaking at his first news conference as manager at Old Trafford, Mourinho hinted that was not where he saw his future.
