I hope he does very well, some people were frustrated by Houllier after the success started to dry up, but there is no denying he is a nice bloke and fairly good manager.
bad move by Lyon if you ask me, there the most attacking team in France and they get Gerrard Houllier as manager dosnt make any sense to me, they already have a succesful system in place and they go and appoint a manager who manages in the complete opposite way!
