Leroy Sane says Manchester City's victory over his former club Schalke was a bittersweet experience.
Two first-half penalties from Nabil Bentableb put City behind at the break but late goals from Sane and Raheem Sterling helped 10-man City fight back to win the first leg of their last 16 tie 3-2.
And the German international admitted it was a somewhat confusing experience to score against his boyhood team.
"I was a little bit sad for Schalke, because the atmosphere was amazing like it always is," Sane said.
City scored twice in the last four minutes to turn the game around after leading 1-0 but then conceding two penalties in seven minutes.
The English champions were left with 10 men in the 68th minute when Nicolas Otamendi was sent off following a second booking.
"You can see the will is a lot, we never give up, we always want to keep fighting," the 23-year-old added.
"Schalke did really well, the way they defended made it difficult. At the end we did it, we scored three goals away - that was the most important thing."
The return leg is on March 12. Before that City can claim their first trophy of the season when they take on Chelsea in the League Cup final at Wembley Stadium on Sunday.
