Ange Postecoglou, deep in thought, was still shaking his head in disbelief as he stepped onto the field at the conclusion of the match.
Swansea had just pulled off an remarkable comeback to advance to the EFL Cup fourth round, netting twice in the dying moments of added time.
The Forest striker scored his first goals for the team to earn a comfortable half-time lead, but Postecoglou will have to wait for his first victory in charge.
Postecoglou appeared to take accountability for the breakdown, pointing towards himself as he went to thank the traveling supporters.
“It was a difficult evening for our fans,” Postecoglou said. “We’ve been eliminated we ought to have progressed in.”
Before Zan Vipotnik leveled the score in the 93rd minute, it appeared that the manager would secure his first win.
The home side were shocked when the striker made it even, and reeling when Swansea’s skipper, the defender, netted his winning goal in spectacular fashion.
“I had Malick Yalcouyé jumping on my back,” Alan Sheehan said. “I kept an eye on the time because Forest that can score from anywhere.”
The situation seemed dire for the Championship side when, down by two first-half goals, the manager brought on impact players.
However, Burgess reduced the deficit soon after, heading in a set-piece.
Andy Fisher made a big save to deny Callum Hudson-Odoi, but Forest failed to capitalize to wrap up the win.
“We are going to have to earn everything,” Postecoglou stated. “It’s not just going to come to us.”
