Diogo Dalot hopes to earn his place in the Man United squad.
The 21-year old defender is on a season-long loan at AC Milan and admits he has unfinished business with the Red Devils.
He has made 11 starts in Serie A this campaign, with Milan comfortably sitting at the top of the table.
Dalot has struggled for form and fitness at Old Trafford and has fallen down the pecking order since the arrival of Aaron Wan-Bissaka from Crystal Palace last season.

Dalot told Record: “Of course, the feeling is a little deeper, more because I didn’t have the time I liked physically. I had great moments at United. I played very important games for me and the team.
“I left with a bit of a bittersweet feeling for not being physically available for all those games I lost due to injury but it is what it is.
“I wouldn’t change anything because what I learned was very important for my future and how I am now. I don’t regret it or look back with disappointment.”
Dalot added: “It is always positive to see the feedback from Milan fans and the affection that United fans have for me. It’s fantastic to feel that.
“But my focus is solely and exclusively on the present. The gift is Milan and helping the club to fulfil its goals and mine. It wouldn’t be professional to be otherwise.”
