Houllier's management has come under intense pressure in recent weeks with many Villa fans calling for his dismissal with the club embroiled in a relegation battle.
Sportsmail reported last week that eight senior Villa players were upset with new rules laid down by Houllier and would be seeking to leave the club in the summer, but goalkeeper Brad Friedel - one of the potential mutineers - and Houllier's assistant Gary McAllister have since come out to deny the claims.

The Villa boss believes the club's fans, who called for him to be sacked after the home defeat by Wolves, have a big part to play in the battle to avoid relegation.
Villa are only one point ahead of the drop zone ahead of Saturday's clash with Everton at Goodison Park.
Houllier said: 'We know exactly where we stand and the difficulty of our task.
'You have to remain positive. You can't spend your time reflecting on what happened.
'We have eight games ahead of us now and never mind what has happened in the past.

'Everybody is concerned because we are not dreamers.'
Villa have finished sixth in each of the past three seasons and are one of only seven clubs never to have been relegated from the Premier League.
Yet despite their Premier League pedigree and a squad including England stars Ashley Young, Darren Bent and Stewart Downing, relegation is a very real threat.
But Houllier is remaining defiant, he said: 'There is a new league starting up for us of eight games and the mood is positive.

'A lot of players are internationals so they have that experience and they know what pressure is.
'I also know their personalities and they want to do well for the fans and the club.'
Houllier added: 'I can really share the fans' frustration and anxiety.
'But their influence is so important for us, especially at this stage of the season.
'They are fantastic supporters and, with their support, they can be the 12th man every game.'
