Houllier, Eriksson tells Chelsea's Grant to get qualified
Houllier said: "If you do not have a driving licence you cannot drive. If you do not have the certificate to be a doctor you cannot practise."
Manchester City boss Sven Goran Eriksson passed his exams while still working in his homeland, and he is adamant that all managers must be qualified to do their jobs.
"In Sweden there were four stages to become a coach at the highest level," he added.
"It is very good and I think it's important that we warrant this job, we have to have it (the licence)."
