Gerard Houllier was due to meet the players before flying back home to tie up the loose ends with the French Football Federation after quitting as their technical director to take over at Villa.
He will not be in charge of Monday's game at Stoke or next Saturday's home match with Bolton - although he hopes to attend.
Houllier is hoping to be at the helm for the Carling Cup game with Blackburn on Wednesday week although he will be assisted by caretaker boss Kevin MacDonald.
Houllier said: "I have to go back. I have a very important meeting Monday, Tuesday, Wednesday. Even if I wanted to take a private jet out (to the Stoke game) it wouldn't be possible. I apologise for that but I will be watching the game on television.
"If all goes to plan the Carling Cup match with be the first game I pick the team for. But I will do that with Kevin obviously. I think Kevin will stay alongside me (for that game)."
MacDonald has already indicated he does not want to be part of Houllier's first team coaching set-up and will instead return to his role as reserve team manager.
