Atzili's first came after only seven minutes when Pierre Cornud's cross bounced off Atzili's back and crept in.

The second saw Atzili fire a shot into the top corner after a bright run and pass by team-mate Frantzdy Pierrot.

Juventus only have three points from their four matches, after they had beaten Maccabi Haifa 3-1 at the Allianz Stadium last week.

Massimiliano Allegri's side now have to win at Benfica on 25 October and at home to Paris St-Germain on 2 November to have any chance of making the last 16.

PSG and Benfica drew 1-1 in the other match in the group and are now level on eight points.

For Maccabi Haifa, this was their first Champions League group-stage victory since a 3-0 triumph over Manchester United in October 2002.

Two-time European champions Juventus are also struggling domestically after a 2-0 loss to AC Milan on Saturday left them eighth in Serie A, 10 points behind leaders Napoli.
