VfB Stuttgart's Kevin Großkreutz faces former employers Borussia Dortmund for the first time since leaving the club in Tuesday's all-Bundesliga DFB Cup quarter-final clash at the Mercedes-Benz Arena (kick-off: 19:30GMT/20:30CET).
The Dortmund-born utility man won two Bundesliga titles and the DFB Cup during a memorable six-year stint with BVB before joining Turkish outfit Galatasaray AS last summer. He returned to the Bundesliga circuit on a six-month loan deal during the winter transfer window, however, having not made a single appearance for his parent club, and now faces the club of his heart.
'Really up for it'
"It's going to be a special feeling facing Dortmund for the first time," the boyhood BVB-fan told www.vfb.de. "I'm really up for it. We want to give our all, with the fans behind us, in the hope of achieving a shock result."
It is not just the prospect of getting one over on some of his old Dortmund teammates that has Großkreutz so fired up. Since being thumped 4-1 by Dortmund on head coach Jürgen Kramny's debut Bundesliga outing, Stuttgart have gone an impressive six competitive matches without defeat - including wins in their last four.

Tuchel preaches caution
By the same token, last season's beaten DFB Cup finalists Dortmund are hardly suffering in the form department. Die Schwarz-Gelben - and through to the last 32 of the UEFA Europa League - have only failed to find the net once against Bundesliga opposition all season and are unbeaten in their last 11 matches against Stuttgart.
That being said, Dortmund head coach Thomas Tuchel did admit his side would have to be careful of how they go about their task, in light of Saturday's goalless draw with Hertha Berlin and Die Schwaben's recent resurgence.
"We lacked organisation and were slow to react [against Hertha]," the former 1. FSV Mainz 05 tactician conceded. "It's going to be difficult playing VfB given the run they're on and with them having found the right balance between defence and attack. We won't win if we can't keep their counter-attacks under control."
