Celta Vigo is a proud footballing institution with nearly a hundred years of history, yet with no pieces of major silverware won during their existence.
They are the biggest club in Spain never to have won anything and that record, coupled with their relative inexperience in Europe, means that their first ever continental semi final on Thursday evening is arguably the biggest game in which the club has ever been involved.
For Manchester United, of course, the Europa League has generally been viewed as an irrelevance, yet the prize of a direct spot in the Champions League group stages for the winners has meant that is has become considerably more significant for a United side currently sitting fifth in the Premier League.
Jose Mourinho's men are slight favorites to claim a first leg win in Vigo with dabblebet offering them at 8/5 (2.60), yet Mourinho will know just how tough a place the Estadio Balaidos can be for fancied visitors.
During his final season at Real Madrid, the Portuguese coach lost a Copa del Rey game 2-1 in Vigo, while this season Celta have beaten Madrid at home in the same competition and also beaten Barcelona 4-3 at home in La Liga.
Celta are a side that can be supremely exciting going forward, yet at the back they remain extremely susceptible and United may feel that they are more than capable of claiming an away goal even accounting for the absence of Zlatan Ibrahimovic. The price of 9/5 (2.80) for a home win, however, looks to offer some value and perhaps the hosts have been underestimated a little by the bookmakers.
What also looks tremendous value is over 2.5 goals at 11/8 (2.38) with matches involving Celta generally seeing plenty of goals. In La Liga, their games average 3.12 goals, while defensively they have the fifth worst home defensive record in the division.
In the previous round they beat Genk 3-2 at home, and while United are a tougher prospect that the Belgian outfit, it is easy to see another high-scoring game.
