All the latest news and gossip from The Emirates Stadium this morning.
Campbell bagged the second goal with a crisp curling effort and his overall performance left United struggling for large periods of the game.
And now he has announced his desire to return to Arsenal from his loan spell at the end of the season:
“As soon as Arsenal came, I wanted to join them and I believe I am ready to play for Arsenal next season. I know I have the capacity to play there. I am only waiting for the opportunity. With hard work I know I can get there. United showed an interest in me when I was moving to Europe but I have been an Arsenal fan since I was a child and that’s why I chose them.”
Arsenal’s decision to recall Chuba Akpom from his loan spell at Coventry City for their important youth ties seems to have paid off.
Jon Toral, Kristoffer Olsson and Serge Gnabry scored the goals but it was the performance of Akpom that grabbed the most attention.
They face Barcelona in the next round.
Spanish reporter Guillaume Balague claims that Alvaro Morata has agreed a deal that will see him move to Arsenal - if the two clubs can agree on a fee.
Balague said on Twitter:
“Morata has agreed to join Arsenal IF, I repeat IF, I insist IF, clubs agree fee. He will push for Madrid to accept Arsenal's offer.”
Johan Djourou has revealed he wants to sign for Bundesliga club Hamburg SV on a permanent deal. He has been on loan at the Imtech Arena since the beginning of the season - and despite their precarious relegation fight and financial position he stated:
"I know the coach, I love the club, I love the city. HSV is incredible. If all goes well and the club also want to, I would stay."
