I'm not Crossie, but German media seems to be in agreement that he is the front runner.
About a week ago Kicker (reliable) reported as much, though according to them no papers had been signed at that point. And Bild (not reliable) reported that Nice is already planning without him for the next season and supposedly is telling potential signings as much during negotiations.
Thanks, he was described as the front runner in France but it has been quite since. Could you see someone like Tuchel join Monaco if Jardim was to leave?
