text: Manchester United fans are done with Jadon Sancho after spotting the first thing he did at Borussia Dortmund's training complex.
  Sancho hasn't played since coming off the bench in a 3-2 win over Nottingham Forest in August and is looking to resurrect his career.
  A return to Dortmund, who he represented between 2017 and 2021 before moving to Old Trafford in a £72 million transfer, was seen as the best option for him.
  The England international won the DFB-Pokal with Dortmund in his first stint and hopes to help them qualify for the Champions League this term.
  Edin Terzic's side sit fifth in the Bundesliga, six points behind RB Leipzig.
  Sancho told Dortmund's official website: "When I walked into the dressing room today, it felt like a homecoming. I know the club inside out.
  "I can't wait to see my teammates again, to get out on the pitch, play with a smile on my face, set up goals, score goals and help BVB qualify for the Champions League."
  The first player Sancho embraced when he entered the dressing room was captain Marco Reus, who looked pleased to see the winger. Sancho's actions just before that are what's causing the controversy.
  He looked directly into the camera and kissed the Dortmund badge despite still being a United player on the books.
  Sancho is expected to join up with Dortmund's mid-season training camp in Marbella and could make his second debut for the club in Saturday evening's game with Darmstadt.
  Dortmund will cover the majority of Sancho's wages during his time at Signal Iduna Park.
  Sebastian Kehl, Dortmund's sporting director, said: "Jadon is an absolute difference player and I’m looking forward to seeing him back in black and yellow soon. He knows this city, Signal Iduna Park, our fans and our club.
  "Even though he hasn't played any competitive games in the past few months, we are sure that he will quickly settle back in with us, get into top form and use his qualities to help us achieve our goals for the season."
