Jose Mourinho has confirmed that he will look to bolster his Manchester United squad with attacking talent in the summer transfer window.
Sunderland needed to return for the second half with the first intention of avoiding conceding a second but they only held out for 45 seconds after the restart as United effectively made sure of the three points.
"Not a brilliant performance but a comfortable one".
Manchester United manager Jose Mourinho finally issued some unqualified praise for Luke Shaw, as the England defender contributed substantially to a win which heaps pressure on Arsenal ahead of the North London club's match at Crystal Palace on Monday night. It resumes its campaign with a quarterfinal first leg in Belgium against Anderlecht on Thursday.
It was vital for United to win at the Stadium of Light after back-to-back home draws to keep in the hunt for a Champions League spot through the Premier League.
Mourinho told The Guardian: "We need to improve our squad, our football is not bad but we are very far from where I would like us to be. I don't want to really focus on the referee and I don't want to make out it's the referee's fault but I think the decision had an impact on the game". "We resisted the results of yesterday when Manchester City and Liverpool won".
"We were hanging in the game and trying to do our best".
The Swede's superb 30th-minute finish, his 28th goal of the campaign, handed the visitors an advantage which grew significantly when compatriot Sebastian Larsson was dismissed for a challenge on Ander Hererra two minutes before the break.
Shaw ultimately played an hour against the Black Cats in which he created four chances, one of which set-up Mkhitaryan to double United's lead moments into the second half, as well as winning 40% of his duels.
"It was important for us to win and that was the main objective. Afterwards we play with one more, sometimes it can be more hard and sometimes it can be an advantage".
"Every player should receive some criticism because we aren't flawless, so we have to accept the criticism from the coach and keep on working because the most important thing is to work and improve and gather experience".
