Could have taken a spot in the stands for the game, such was the level of his involvement.
Another encouraging display from the young defender, who slotted in effortlessly at left-back in the absence of the injured Schmelzer.
The Germany international was comfortable throughout playing alongside Subotic, and kept his concentration well to avert any danger.
A straightforward day at the office for the centre-back, as Freiburg struggled to create any chances of note.
The shining light in Dortmund's impressive display. He grabbed both goals before the interval, the first a well-taken chip and the second an ice-cool penalty into the bottom left corner.
Pushed forward well down the right-hand side for the hosts, and supplied some enticing crosses for Lewandowski.
Metronomic in the centre of the Signal Iduna Park. The former Real Madrid midfielder looks so at home back at Dortmund and his fine form for the Bundesliga giants continued today.
The summer signing exploited the gap between Freiburg's defence and midfield well before being withdrawn midway through the second half.
Subbed off at half-time for Kirch after picking up a knock early in the game. He looked out of sorts after falling awkwardly and it was no surprise that he was withdrawn at the interval.
Unfortunate not to find the back of the net in the first half, as Baumann pulled of a series of impressive stops, but made up for that after the break with a fine double.
His blistering pace unnerved Freiburg's back line throughout but his finishing was surprisingly wayward given his previous clinical showings so far this season.
Pulled off a string of wonderful saves from Lewandowski in the first half, and was unfortunate to find himself on the wrong end of such a scoreline.
At fault for Dortmund's fourth and fifth goals as Hofmann glided past him before setting up Lewandowski and then Kuba brushed off his weak challenge and shot into the bottom corner.
Provided an outlet down the right-hand side for the visitors but was too often wasteful in possession.
The centre-back was all over the shop after the break following Diagne's dismissal and too often he let the likes of Lewandowski and Aubameyang burst past him.
Dismissed on the brink of half-time for hauling down Lewandowski as the Poland international hurtled through on goal.
Impressed in patches in the first half against a superb Dortmund midfield, but dipped after the break following Diagne's sending off.
The captain was outclassed in midfield by Sahin and Kirch, as Dortmund ran riot, particularly in the second half.
Wasted a great opportunity to test Weidenfeller with a free kick in the first half, which turned out to be Freiburg's best chance of the game.
The former Arsenal midfielder gave the ball away far too easily far too often over the course of the game. It came as no shock that he was the player withdrawn at the break.
A periphal figure for much of the game. The attacker had one chance midway through the first half that he wasted, shooting straight at Weidenfeller.
Like Mehmedi, he did not do enough to cause Dortmund's defence problems and was another player that can have no complaints about being withdrawn after the break.
Very neat and tidy in the second half after replacing the injured Bender. A decent showing from the 31-year-old.
Supplied a perfectly-weighted assist for Lewandowski's second goal.

Brought on to try and shore up the Freiburg defence at half-time following Diagne's red card but he failed to do that as Dortmund ran riot.
