CELTIC’S second leg Europa League tie with Zenit St Petersburg is heading for a sell-out.
Brendan Rodgers side will host their Russian opponents on Thursday night at Parkhead and the two teams will go head to head a week later for the right to advance to the last 16.
That encounter will take place at the Saint-Petersburg Stadium in front of what is expected to be a 56,000 capacity crowd, with only 2,838 seats left to be filled.
Zenit have the highest attendances in the Russian Premier League this term with an average of 44,578 in their nine home league games.
The stadium opened last summer at the cost of around £791million.
