The Spanish forward, 21, has made two appearances this term - in the Europa League win at Young Boys Berne and the Capital One Cup victory at West Brom.
Pacheco, signed in 2007 after coming through the Barcelona ranks, is full of confidence he can be the next off the conveyor belt.
He insisted: "I hope this is a new opportunity for me. We have already seen he is giving a chance to the youngsters so, hopefully, I will get one in the next few games. I've played a few matches and think I did quite well, so hopefully by working every day I can get back in again.
"I was supposed to go on loan to Spain in the summer but it didn't happen, so I went to see the manager.
"He said he'd treat me as a professional and an adult.
"He has given me the chance to try and impress him - so now it is my job to do my best."
