Johnnie Jackson wants more clarity on his own future before he can proceed with contract talks with Charlton players: https://londonnewsonline.co.uk/charlton-athletic-boss-needs-clarity-on-his-future-so-that-squad-plans-can-take-shape-for-longer-term/
As I recall his contract renewal depended on achieving certain targets although these were never made public. In terms of points per game he has done well.
Richard Cawley states that the contract renewal is based on final league position. He added: 'I think Sandgaard will wait to see how we do now the new manager bounce effect is over. Hopefully he can still motivate the team to perform for him until the end of the season. Fraser will help improve performances too, I believe.'
