The Spanish starlet figured for the final 13 minutes in Turkey and it was his initial shot that led to Dirk Kuyt's 88th-minute winner.
Pacheco told liverpoolfc.tv: "We are very happy. We worked very hard to get the result as we were losing at half-time, but we came back and did very well.
"It was another appearance for me. I played 15 minutes and I think I can be happy with myself. I will keep working and hopefully I can get more minutes.
"I need to keep working hard and training and try to take the chances Roy gives to me."
