United did not finish lower than third in the Premier League era under Sir Alex Ferguson, but since his retirement have ended seventh, fourth, fifth and sixth.
Last season, Mourinho eventually had to prioritise the Europa League over the Premier League in a bid to secure Champions League football.
Mourinho has added Romelu Lukaku, Nemanja Matic and Victor Lindelof to his squad this summer as he puts together a group of players capable of challenging in the Premier League and Champions League next season.
I, for one, am glad to see the Premier League return!
"It's not just hope it's convinced that the quality of the team will be better, I have conditions to deliver a better one than the first". "If the remaining 25 per cent don't arrive I will not moan, I will just go with everything I have to try to win every match I play". The players, they know you. We are not happy that we lost but did everything. "We had an opportunity to equalise, Marcus had a good chance and didn't score, unluckily for us, but this is football".
And Matic has called on his side to hit the ground running when they begin the new season at Old Trafford on Sunday. The one thing you don't want is space between the full-back and the centre half. We'll take it step by step and be humble.
"I just think that he was very clear by showing that what he did past year was not enough for him".
He achieved the feat at Porto, Chelsea twice, Inter Milan and Real Madrid, with the only exceptions to the rule being his first two management roles, at Benfica and Uniao de Leiria, where he lasted less than a season in both cases. The game will show how well manager Arsene Wenger has prepared to fight back into the top four after they missed out last season.
Manchester United showed glimpses of what they could do against an nearly full strength Real Madrid in the second half in Skopje - and they looked as cohesive and unsafe on the break as they have been in the last few years.
"It's my old club with my old fans and my old stadium, so probably I can not celebrate", he said.
Brighton, who returned the top tier after a 34-year absence by finishing second in the Championship, last hosted City in a 2008 League Cup tie.
Defeat by Real Madrid in Tuesday's UEFA Super Cup match in Skopje was a setback, but Mourinho says his team are ready for the new season.
Five of West Ham's last six Premier League goals against Manchester United have come from set-pieces (one corner, four free-kicks).
