Celtic fans are likely to sizeably outnumber Lazio fans at the UEFA Europa League clash in Rome on Thursday.

The Italian Serie A club has reported slow ticket sales leading up to the group stage match, with only 14,000 tickets sold for the match at the 70,643-capacity Stadio Olimpico.

Lazio marketing director Marco Canigiani said that the Scottish Premiership champions have purchased 9,000 of the tickets sold so far.

That equates to around 65 per cent of supporters in attendance will be cheering for Celtic, with an estimated 6,000 additional fans traveling to Rome without a ticket.

Talking on Lazio Style Radio, Canigiani said: “A bus service will be available for Lazio-Celtic, but it’s directly proportional to the demand from the fans for this match.

“For the game on Thursday we’ve sold over 14,000 tickets but the majority of that number has gone to Celtic. We expect a growth in sales of those available to Biancocelesti fans.

“Thursday will be an important match in terms of qualification, the team will need support for it.

“The prices are also very reasonable for Thursday’s match, hopefully we can be in the majority at the Stadio Olimpico considering there will be around 9,000 fans from Scotland in the away end.”

UEFA has forced Lazio to close a section of the stadium down after being found guilty of racist chanting during the Europa League group match against French Ligue 1 club Rennes.
