Becoming the first United manager to finish on top of the pile since Sir Alex Ferguson is great motivation for someone with his pride and ego, and numerous troubles that afflicted his first season, despite winning two cup trophies, have disappeared.
Ibrahimovic -- who had won league titles with every club he had played for before joining United on a free transfer from Paris Saint-Germain a year ago - has made clear that he was disappointed to finish sixth with Mourinho's team last season.
"It is not because I have always done it [won the league title in his second season] that I am going to do it again", Mourinho said.
The Red Devils often struggled to find a way past teams last term, when Zlatan Ibrahimovic provided the key impetus with 17 Premier League goals, although no other player was able to reach double figures.
"I don't think I am going to win it because I always win it in the second season".
"What would it mean for me to be the Premier League champion?"
He doesn't need time to adapt, he's not a young guy coming from another country, he doesn't need to learn the Premier League, ' added Mourinho. It's not just for his qualities but my relation with him and the way I know him'.
United will kick off their Premier League season against West Ham at Old Trafford on Sunday, with Mourinho suggesting his side can win the league.
The United manager had outlined four positions he wanted to strengthen in to executive vice-chairman Ed Woodward at the start of the transfer window, but only Victor Lindelof, Romelu Lukaku and Nemanja Matic have arrived at Old Trafford.
Matteo Darmian is likely to start ahead of Daley Blind at left-back, and Antonio Valencia should captain the side at right-back after Timothy Fosu-Mensah was loaned out to Crystal Palace.
While Mourinho has welcomed the new signings, he argues that of greater significance is the fact his team will not have their domestic fixture list disrupted by the Europa League this season.
"I trust he is going to perform, so I think he is a fantastic signing". The top seven, we are all in Europe.
If Mourinho is feeling the pressure of maintaining his record of winning league titles within two years at Porto, Chelsea (twice), Inter Milan and Real Madrid, he's not showing it. My hard work to motivate people to play in the Europa League with ambition and responsibility was hard.
"Twenty-five per cent means one of four".
