Jones said of Hammam
"I think the decision Sam has made is the right one and he admits that.
"It's the saddest saying there is: 'the king is dead, long live the king' and everybody does move on, but Cardiff City can go forward now.
"The good thing is that it's not like someone coming in from outside who doesn't know the football club.
"Peter's taken over so that keeps the continuity going and we can all deliver what everyone wants.
"I got on well with Sam, he brought me here with Peter, he was a football person and the things that he's done have been fantastic for the club.
"Along the way Sam will say that he made mistakes, but everyone does that anyway."
Of more concern to Jones will be getting side ready to make up for the defeat at Norwich last Saturday. That result was lost in the melee that followed with news of Sam's departure.
City lead the division by three points but that could be cut to zero tonight if Preston beat Burnley.
