Former Israel international and one-time Celtic target Itay Shechter mocked the Hoops' Champions League exit live on TV after their Bayern Munich heartache.
And the former Swansea City and Nantes star even broke into a song to celebrate Bayern's injury time leveller.
Former Celtic star Eyal Berkovic launched a vicious attack on Celtic and Irish fans this week after their 'Show Israel the Red Card' banners last week in the first leg of the play-offs.
And countryman Shechter - who is now a TV co-commentator after winning 27 caps for his country and also playing for clubs like Kaiserslautern, Maccabi Haifa and Beitar Jerusalem and who once claimed that Celtic made him an offer when he was at Hapoel Tel Aviv,- couldn't hide his delight when Alphonso Davies netted that injury-time equaliser to send Bayern through 3-2 on aggregate.
He screamed: "Yes! Come on! Go home Celtic.

"It's even better when the goal is scored as late as that!"
He then bizarrely started singing: "Glory be to God, always loves me, and always has only good things for me."
Berkovic said earlier this week: "I took down all the pictures from me at Celtic on my social media.
"Celtic fans identify with the Irish. Celtic has a connection with the Irish who are against the Jews, in short, they have crazy hatred towards us.
"I kept saying about Robbie Keane when he was a manager here that he should leave because if he speaks for Israel he will endanger his family in Ireland and people didn't understand why. The Irish and the Scots hate us.
"As a player I didn't feel it, only at the end of my career. When they hate someone, they are bad."
