The Hoops face one of the smallest teams ever to play in the league phase of European competition later this month when they play Torreense.

The game will be played in Leiria, 50 miles away from their home of Torres Vedras, because their 2,000-capacity stadium is not suitable.

They made history last season when they defeated Sporting Lisbon in the Portuguese Cup Final under boss Luis Tralhao.

But they have sacked him and replaced him with former Estrela da Amadora manager Joao Nuno instead.

Torreense are languishing in 12th place in the Portuguese second division after a disastrous season so far domestically.

However, they made history when they won in Norway against Lillestrom in their opening game and were only defeated by Sunderland after an injury time goal.

They play Armenian outfit Ararat-Armenia this week - the only team behind Celtic in the table, on goal difference - before welcoming the Parkhead side at the end of the month.
