Chris Greenacre will take charge of the Wellington Phoenix for at least their next A-League fixture against Sydney FC.

The club legend moves back into the interim coaching role for a remarkable fourth time, stepping up from his role at the club's academy.

He is in ongoing discussions with the club about the head coaching position for the rest of the A-League season - and beyond.

Wellington Phoenix Director of Football Shaun Gill says the plan is to get through this week first, and then finalise some details.

"There's not a contract in place for him for the role at the moment, but he's prepared to jump in and we'll finish those discussions in due course."
