The Ecuador international winger is on loan at Wigan from Villarreal and he has made a real impression on Bruce.
"Valencia has done extremely well," said Bruce. "I am going to make sure I do everything I can to make this a permanent signing."
Bruce has also revealed that he has informed Austrian Paul Scharner that he will get the chance to claim a regular spot as a centre back.
"I tried to sign Scharner when I was at Birmingham as a centre back," said Bruce. "That is his position, in my view, and players have got to do it my way.
"I watched him play there for his country and I also saw him in Bergen. I was disappointed when I missed out on him but, credit to Wigan, Dave Whelan came up with the cash and they nicked him."
