Jardim is set to lose his job after suffering seven defeats in nine matches and sources say Henry is on a very small short-list of successors.
Henry, who graduated from Monaco's academy to play 141 games for the club, was guest of owner Dmitry Rybolovlev for last month's Champions League loss to Atletico Madrid at the Stade Louis II. Monaco are now understood to be exploring a return for the 41-year-old as manager.Sportsmail revealed last week how Henry was Villa's choice to succeed Steve Bruce and detailed talks have taken place with the former Arsenal striker. Villa co-owner Nassef Sawiris, who used to have a season ticket at Highbury, wants Henry in place.
It appears Henry is still weighing up his next move and he was yesterday out training with Belgium in Brussels in his role as assistant to Roberto Martinez.
Villa have been discussing the possibility of bringing in Henry with John Terry as assistant and Sportsmail understands the former England captain has told friends he is keen to return to the club he played for last season.Developments in Monaco raise the prospect though that Terry could still become Villa manager, particularly if Henry decides to take the soon-to-be-vacant post at the Ligue 1 club.
New chief executive Christian Purslow is leading the appointment process and wants a conclusion by the time of the side's next game against Swansea on October 20.
It is understood Juan Garcia Pitarch, formerly of Valencia, began work as Villa's sporting director yesterday and will also be involved in negotiations.
