Can had previously represented Liverpool for four seasons but left the Reds for Juventus in 2018 and was loaned out to Dortmund this January.
His allegiance with the Reds prevented him from joining United, who were eager to secure his services in the winter transfer window.
Speaking to Goal, Can revealed that his Liverpool connection meant he never even considered a move to Old Trafford.
“I had three offers from the Premier League alone, including from Manchester United, but I didn’t think about that for a second because of my Liverpool past.”
“I have always had an extreme sympathy for BVB. I wanted to go to a club for which I can be important where I am needed. That’s the case in Dortmund. Borussia suits me well – and vice versa.”
Can has gotten his Dortmund career off to a solid start, scoring on debut against Bayer Leverkusen.
