Lerner and chief executive Paul Faulkner instructed Houllier to make up with Dunne and other senior stars, including Stephen Ireland, after fearing that low morale would drag Villa into a relegation battle.
The Frenchman has won only three of 14 league games since replacing Martin O'Neill and stripped Dunne of the captaincy, axeing him from the side after the defender clashed with assistant manager Gary McAllister in training.

The hierarchy urged Houllier to sort out the problems following a miserable 4-0 defeat at Manchester City.
Dunne will be back at Stamford Bridge and there will also be a place in the squad for midfielder Ireland, who has handed in a transfer request and not featured since a 3-0 defeat at Liverpool a month ago.
Houllier will accommodate the two players and may even try Luke Young in an unfamiliar role at left-back.
