Sancho, meanwhile, wrote his name into the Bundesliga history books on Saturday as he became the youngest player to record 50 assists in the competition.
He inspired his side to a comfortable 3-0 win over Arminia Bielefeld, kicking off proceedings by setting up team-mate Mahmoud Dahoud for Dortmund’s opener.
Sancho then converted from the penalty spot soon afterwards to double his side’s lead.
Real Madrid loanee Jesus Carvalho added a third 10 minutes from time after being set up by Haaland.
Like Sancho, Haaland is also widely coveted, with Manchester City and Chelsea believed to be keen on landing the Norway striker.
