Guus Hiddink is set to return to Chelsea as interim manager for the second time, says former Blues striker Mateja Kezman.
The Dutchman managed Chelsea in 2009 and won the FA Cup in a largely successful spell, and has been heavily linked with reprising the role following the departure of Jose Mourinho on Thursday.
However, Kezman, who played under Hiddink at PSV, claims a deal is already in place.
"I don't know if it's confirmed, if the club has announced it, but Guus told me earlier," Kezman told Croatian tabloid Index.
"He is a top coach who knows what to do every time. He knows when to tighten the belt, but also when to loosen. He is a good coach and even better psychologist.
"I'm convinced that with him Chelsea will recover and rise in the table, and I'd also say they are one of the favourites for the Champions League.
Kezman added that he was not surprised to see Mourinho leave Stamford Bridge, insisting the club's "catastrophic" start to the season could not be allowed to continue.
"It's incredible that a team that were champions last year are now fighting for survival.
"That's why I think Roman's decision is right and Guus Hiddink is a great choice."
