In a lengthy message posted on Instagram, Sancho writes: “This is a hard message to swallow.
“First of all I just want to start off by thanking Borussia Dortmund for everything they have done for me, taking the risk on a young 17-year-old at the time with no first team experience and believing in me.
“The love I will always have for this iconic club will never be matched. From the very first moment I walked into the stadium I felt at home and knew I had made the right decision.
“I was welcomed with open arms by everyone associated with the club. Moving to Germany was not only football, I had to adapt to a new lifestyle and culture.
