Manchester United could reportedly be hindered in their pursuit of Borussia Dortmund star Erling Haaland due to a clause for team-mate Jadon Sancho.

The Red Devils have been linked with both stars in recent seasons and grew frustrated over their pursuit of Sancho during the summer.

Now it appears that Haaland is their top target having been keen in signing the Norwegian while he was at RB Salzburg.

Though Manchester City are also keen, and reportedly hope to use a Sancho sell-on clause to beat their local rivals.

It’s reported that Pep Guardiola’s side could agree to waiver or renegotiate that in order to gain an advantage over other clubs pursuing Haaland.

With Dortmund valuing Sancho at around £120m, the 15 per cent sell-on could be worth as much as £18m to the Bundesliga giants.

City are believed to be waiting to hear if Haaland is available this summer, though he can leave in 2022 for a fixed buyout clause of £65m.
