Celta Vigo will be backed by their biggest away support for a European match in their history, with 3,000 fans at Celtic Park. They have sold 3,000 tickets for the game in Glasgow - which surpasses the 2,500 supporters they took to Old Trafford for the semi-finals of the Europa League against Manchester United nine years ago and the 2,900 fans they had with them in Lyon last season for a Round of 16 defeat. Celta Vigo's director of infrastructure, Carlos Cao, said: "In Glasgow they don't understand why so many people from Vigo want to go to the game. For them, it's just another game, but it is a very special match for our supporters. "Lots of our fans bought a ticket first, then worried about travel and a hotel later!"
