"We are talking about players now very firmly in the limelight: Ashley Young, Gabby Agbonlahor... and one never knows.
"For us to try and realise our own particular ambitions we want to try to strengthen our side, not lose players."
Captain Gareth Barry was quoted as wanting Champions League football, however O'Neill will not make a knee-jerk reaction over the comments.
The Villa boss wants Barry to see out the season in his current form before discussing his long-term goals and objectives behind closed doors.
"The best thing to do would be to sit down with Gareth at the end of the season," O'Neill continued.
"That's the only sensible thing to do. It is part of the job - we will see where we go. He has got two years left to run."
