Borussia Dortmund superstar Erling Haaland is facing an injury sweat after pulling up during his side's 3-2 win over Hoffenheim.
The 21-year-old netted the opener on Saturday but was left in agony during the second period with a muscle complaint.
And that leaves him fighting to be back ahead of a jam-packed fixture run, after a self-inflicted mine break due to being unceremoniously dumped out of the DFB-Pokal Cup.
