Celtic boss Neil Lennon has called on the club's fans to "bring that thunder" for tonight's Champions League clash against Ajax at Parkhead.
The Scottish champions are currently at the bottom of Group H after two defeats from their opening two games.
Lennon tweeted: "The home support is so vital for players on these nights. Being so close to that atmosphere is such a thrill and a privilege. Bring that thunder."
Ajax arrive in Glasgow with one point out of a possible six following a 1-1 draw with AC Milan at the start of the month.
