The England international has attracted interest from several clubs in Europe this summer following a stellar season with the German giants.
Amongst the teams interest in acquiring the former Manchester City academy star’s services are Manchester United, who are looking to overhaul their squad this summer.
United are said to be willing to splash out a staggering £100million to snap up the 19-year-old, who has taken the Bundesliga by storm.
Sancho, however, has dealt the Red Devils a huge blow by revealing he intends to help Dortmund improve on their second-placed finish in the Bundesliga.
“Next season our target is to win, not come second,” the winger said.
“I’m really happy with how I played this season.
“I wasn’t playing that much at the start of the season but was in the team more often later on. It’s all about hard work.”
Dortmund are well aware of the interest in their young asset but have no intention of cashing on him.
“No, we did not receive anything [an offer],” Dortmund’s sporting director Michael Zorc told Sky Sports.
“We do not expect anything and we do not want anything, because he is on our plans.
“He will play for Borussia Dortmund next season.
“Nobody needs to get in touch.”
Sancho has gone from strength-to-strength since leaving City to join Dortmund, scoring 14 goals and picking up 23 assists in 55 appearances for Lucien Favre’s side.
His success in Germany has impressed many, including his England team-mate Raheem Sterling, who reckons young players could learn a thing or two from him.
“He is an inspiration to a lot of youngsters, especially because he is from London and I am from London,” Sterling said.
“I am sure every youngster from London will look up to him and probably (try) to be like him and win big awards like that one day.”
