A Borussia Dortmund insider says he's "sure" Jadon Sancho will sign for Manchester United in this summer's transfer window.

That's according to former Norway striker turned pundit Jan Aage Fjortoft, who says his source at the Bundesliga club is confident the deal is all-but wrapped up.

United have been in hot pursuit of the former Manchester City graduate all season, but recently made a breakthrough in negotiations.

The Red Devils are prepared to pay just north of £60million to sign Sancho, and will then pay the rest of the transfer fee in installments.

The final figure could be as much as £105m, but Manchester United are looking to pay less than £45m in bonuses over the next two seasons

What the final price will be remains to be seen, but one thing that is apparently certain, according to Fjortoft, is that the transfer will take place.

On Twitter he wrote: "Re: Sancho. I was just texting with one of my best sources and insider in Dortmund. We discussed the latest reports and the actions today.

"His last text was: 'I am sure that Jadon will come to Man United this summer.'"

Manchester United are prepared to hand Sancho wages of around £220k-a-week, and the England international is expected to be handed the number 7 shirt.

Sancho's transfer will also pave the way for Alexis Sanchez's permanent move to Inter Milan.
