Celtic legend fears they will be forced to play behind closed doors game after 'attack' on Kylian Mbappe

Celtic legend Charlie Nicholas admits he is ‘fearful’ that his former club will be forced to play their next Champions League game behind closed doors after a fan ran on the pitch and tried to kick Paris Saint-Germain forward Kylian Mbappe.

The Scottish champions have already been punished by UEFA after their fans displayed inflammatory banners and were found guilty of offensive chants, with the club now waiting to see if the fines they have paid in recent months are followed up by a punishment that may see them play their next Champions League game behind closed doors.

The incident with Mbappe was not caught on the TV cameras, but Nicholas told Sky Sports that he is concerned it may spark action from UEFA.

“I am fearful that this could lead to a stadium ban for Celtic and that would be a hammer blow with Bayern Munich coming up next,” said the Scot. “Celtic have been warned by UEFA and punished in recent months and they could not afford this to happen. I would worry for them now.”

Nicholas was also outspoken in his criticism of Celtic’s performance in their 5-0 home defeat against a rampant PSG, as their celebrated front three of Neymar, Mbappe and Edinson Cavani ran riot at Parkhead.

“It was an embarrassment,” declared Nicholas. “Celtic have learned nothing from last season and already they are playing for third place in the group.

“They were miles away from PSG and I have never seen them so badly embarrassed at home. Not good enough.”
