Paco Alcacer scores on his debut as Dortmund beat Eintracht Frankfurt to go top
Jadon Sancho had a hand in two goals from the bench.
Victory takes Lucien Favre’s side top of the fledgling table but Dortmund were far from their best.
The hosts introduced Jadon Sancho and handed a debut to Barcelona loanee Paco Alcacer from the bench but appeared satisfied to attempt to hold onto their 1-0 lead.
That plan came undone after 69 minutes, as they afforded too much space to Sebastien Haller who swivelled to find the bottom corner for his third of the season to draw Frankfurt level.
The Dortmund rally was immediate and they equalised four minutes later. It was a superb move, sparked by a brilliant pass from Marco Reus to find Sancho, whose deft turn and cross teed up Marius Wolf to lash home from 12 yards after a perfect first touch.
And the icing was put on the win two minutes from time, with a debut goal for Alcacer, whose strike deflected in off Haller.
