Bernd Schuster believes former club Real Madrid will need to give more power to their coaches if they want to entice the likes of Arsene Wenger and Jose Mourinho to the club in the future.
With presidential elections taking place at the Spanish giants this summer and current coach Juande Ramos only handed a six-month contract after replacing Schuster in December, speculation is mounting about who will be in charge at the Bernabeu next season.
Carlo Ancelotti, Wenger, Mourinho and Rafael Benitez have all been among those linked to the post in recent times, while Ramos must also be considered a contender after guiding Madrid to 14 wins in 16 league games since taking the reins.
Schuster's own tip for the position would be Arsenal boss Wenger, but the German believes the Frenchman - like other coaches - could be put off by not having complete control over transfers, with Madrid employing a sporting director to oversee that.
Schuster himself has revealed his frustrations at Madrid not signing any of the players he wanted last summer, with the club preferring to concentrate their efforts on trying to bring in Cristiano Ronaldo.
In the second part of an interview with Spanish newspaper Marca, Schuster was asked who he would recommend as coach if former Madrid president Florentino Perez returned to the helm this summer, and the German admitted: "That's very difficult.
"When a big coach is not given control over all the areas we've been talking about, it is going to be very difficult. Now we are talking about someone who I cannot imagine will come.''
Asked if that person was Wenger, Schuster said: "Of course. Now, if Florentino brings in a sporting director, I have doubts if he (Wenger) would accept this. In all his time at Arsenal he has been more than a coach. The same as (Sir Alex) Ferguson or Benitez. These guys are more than just coaches.
"I imagine they would say 'I make the team'. If you put a person above them it could complicate things more than help them. In negotiations, what's going to be their role?
"If you want to bring in a big coach, like Ancelotti, Wenger, Mourinho... why can't you give them sole control and let them get on with it?''
It could be that Madrid will not even look abroad for next season's coach, with Ramos putting forward a strong case to continue in the position.
Aside from their Champions League mauling at the hands of Liverpool and a 2-0 defeat to Barcelona in his first league game in charge, Ramos has overseen an almost perfect run and could yet guide Madrid to the Primera Division title.
An impressed Schuster said of Ramos' Madrid: "They couldn't be doing better. The team is playing more defensively, but this of course means they concede less goals.
"I don't want to compare it with my team as I don't think that would be fair, because playing just once a week you have most of your players available,'' added Schuster, referring to the serious injury problems he had towards the end of his reign.
"For example, I would never have imagined that being at Real Madrid I would have to go into a match with only 16 players. That's unthinkable.''
Madrid's good run under Ramos means they are now six points behind leaders Barcelona heading into the final eight games of the season.
The reigning champions are outsiders to retain the title Schuster helped them win last season, but with a home match against Barca still to come there is hope yet.
However, should Madrid win their third successive league crown this season, Schuster admits he would not accept any credit for helping them on their way.
"If Real Madrid win the title it will be the work of Juande,'' he said. "The important thing is to beat Barca in the Bernabeu.''
