Good addition to the team
Wilson has been a highly-rated graduate of United's famous academy, scoring four goals in 20 senior appearances for the Red Devils.
The 20-year-old impressed many last year in the second-tier of English football, scoring five times in 11 starts for Brighton & Hove Albion.
Wilson returned to the Aon Training Complex this summer, but with the competition of Wayne Rooney, Zlatan Ibrahimovic, Marcus Rashford and Anthony Martial has seen him move out on loan.
Nigel Pearson's side will be looking for a return to the English top-flight, and Pearson shared his delight at the capture of Wilson.
Pearson told dcfc.co.uk: “We’re delighted to have agreed to bring James Wilson the club on a season-long loan," and Pearson admitted to the club's site “I hope that this loan deal will prove to be mutually beneficial for all parties and I would like to place on record our thanks to Manchester United for allowing James to join us."
Pearson pointed out Wilson's strengths saying: “He is an energetic player who will add to our existing attacking options," and is adamant that "He is a really good addition to our existing attacking options."
Couldn't ask for more from United
In terms of United's first team, they have had an excellent start to the campaign, and continued that on Friday.
A double from Zlatan Ibrahimovic saw them earn a 2-0 win over Southampton, and the Portuguese manager said he couldn't ask for more from his side.
Mourinho told Sky Sports that United "were always in control, we won comfortably and the result could [have been] bigger," and the 'special one' believes that "it's impossible to [go] faster than what we are doing. The way we are playing, the kind of football we are trying to play, the way the team is defending."
The Portuguese coach concluded: "It's impossible to demand more from the boys. [There's a] great spirit, everyone is working very hard and I'm pleased."
Manchester United will take on Hull City at the KCOM Stadium on Saturday, August 27 with kick-off at 5:30pm BST.
