"It is pure speculation; I don't know where that one has come from at all," he says of a story in a newspaper on Saturday claiming he would be looking to bring the Chilean midfielder to the club.
As for David Connolly not being happy at failing to make the first 11 at Deepdale - despite coming off the bench to score the winner - he says: "I gave David his debut when I was at Watford. He was an angry ant then, rough and tumble, and nothing has changed."
He denies having an arrangement with Liverpool to pick on-loan Neil Mellor every week and adds: "No one is guaranteed a first-team place at this club, so I don't know where he is coming from on this one.
"We have got three strikers that any manager in the first division would be very happy to have; it is the one part of the team where I do have good competition.
"Neil is being treated no differently to the others, but I pick the team.
"I am not disappointed - it is the world we live in, I have learned to understand that in the last couple of years.
"It was a straightforward decision which as a manager you are allowed to make."
And he says it is does not overshadow the pleasure of winning, insisting that a sense of perspective was needed. Ray Harford died on Saturday after a long illness and Watford's on-loan Jimmy Davis was tragically killed in a road crash as well.
"Impossible, let's get in the real world. Ray Harford has died, look what happened to the boy at Watford, Jimmy Davis, and then there was my own situation last year," he says.
Glenn prefers to concentrate on the positives of the game at Preston, and adds: "I thought Anton Ferdinand, considering he was involved in that first goal on his debut, came through the game well because a lot of young men in that situation would have gone under.
"And Rob Lee and Don Hutchison did well, keeping the team together and retaining possession in the latter stages of the game.
"I felt positive going into the new season but obviously things changed after 90 seconds when they got the goal.
"The victory was a pleasing start, though."
