“Nothing is sorted yet, but I’m confident it will be,” confirmed Benitez.
Standard Liege have confirmed that Juventus and AC Milan are also interested in signing the striker.
“I wish Jovanovic all the best,” confirmed Standard’s vice-president Luciano D’Onorfio. “He always did his best for the club.
“AC Milan, Juventus and Liverpool want him. The choice is up to him. I play no role in his decision.”
