Borussia Dortmund will not sell Jadon Sancho "below value" amid the financial impacts of COVID-19.

Dortmund are holding out for a transfer fee of $143 million.

Manchester United, Liverpool, Chelsea and Barcelona are targeting Sancho.

"I can clearly say that despite the existential crisis [for football] even the richest clubs don't have to believe they can go bargain hunting at Dortmund," Hans-Joachim Watzke said. "We must not sell anyone below value."

And Dortmund have not given up all hope that Sancho will remain at the club for one more season, with Watzke adding: "We've said it before corona already that we favour the idea Jadon stays here. But, at the end of the day, you also must respect what the player wants."
