Since then the manager has plugged the gaps in his team with big new signings.
Mourinho's optimism is based on three beliefs; he feels he has a more settled squad than when he arrived, that they have had a better pre-season than 12 months ago and that their rivals at the top of the division will have greater distractions in European competition this time.
"We have a central midfielder and striker, so obviously another player would be one coming from the sides".
The affliction between the striker and the Red Devils is clear for all to see, Ibrahimovic became a cult hero last season amongst United fans because of his desire to win, his wonderful arrogance and of course his goals.
United have added striker Romelu Lukaku, midfielder Nemanja Matic and defender Victor Lindelof to their squad.
"The West Ham supporters I've spoken to are very happy with the new players".
In search of goals, Manchester United turned to last season's second-highest scorer. The Europa League not the Champions League. "I will try to do my best to stay here, get an important role for the season, to help my team-mates and to impress the manager".
It is very hard to see Mourinho's side being so mediocre again in the league this time around, however, and they have bought solidly this summer.
After seeing three different teams win the past three English Premier League titles, Manchester City is hoping to return to glory this season as the +185 favorite (bet $100 to win $185) on the EPL championship odds at sportsbooks monitored by OddsShark.
"What I had in other clubs was more players scoring goals, what we had was midfielders, wingers scoring, central defenders scoring goals at set pieces", Mourinho said. "We're used to just watching the game and going away quietly, but this time around we could not leave quietly!"
"But they are for wonderful players, so good luck to them if they can do that".
Four Australians featured in the top tier last season but it was the first time since the EPL era started in 1992, when Mark Bosnich had his breakthrough season with Aston Villa, that not one was a bona fide regular. They are: Arsenal, Chelsea, Everton, Liverpool, Manchester City, Manchester United and Tottenham.
'Twenty-five per cent means one of four. But we're in a position to do better quality work than we did in the first season.
'So between what we have lost and what we have got, we're in a similar situation.
Having finished seven points behind Chelsea, Spurs have yet to make a single signing, and Walker's sale to City and a season playing their home games at Wembley adds to Pochettino's problems.
Sky Sports has claimed that the two Premier League clubs are negotiating the transfer of the 21-year-old.
He said: "We have a giant on our chest which is really heavy, but we don't compare to the biggest clubs in Europe right now".
