With Conte's job at Stamford Bridge under considerable threat, however, having won only five of 14 matches in 2018, Costacurta - one of those tasked with making an appointment - is not giving up hope of luring him back for a second spell in charge.
"I haven't chosen yet but I think Conte is the one who could do the best. I'll definitely talk with him in a couple of months," he told Gazzetta dello Sport. "He's already shown he knows how to be national team coach while the others haven't yet.
"That doesn't mean I wouldn't be happy with [Roberto] Mancini or with [Carlo] Ancelotti, although Ancelotti seems to have removed himself from consideration."
Conte guided Italy to the quarter-finals of Euro 2016 before stepping down to take over at Chelsea, winning the Premier League title in his first campaign in West London.
