Union Saint-Gilloise are playing in a European competition again for the first time in 58 years. The Belgian club played in the Fairs Cup (predecessor to the UEFA Cup) five times from the 1950s to the the middle of the 1960s. USG have proved to be very successful on their return to the European stage: The 1-0 defeat against Union Berlin in the group stage is their only loss in the Europa League this term. The overall tally: 5 wins, 2 draws, 1 defeat.
The Werkself have experience in coming out on top against Belgian teams: Bayer 04 have only lost once in seven matches against Belgian clubs with three wins and three draws in the other games. Leverkusen did not concede a single goal in the three home fixtures.
Following four wins in succession, USG had to settle for one point in the Jupiler Pro League at the weekend. The team under coach Karel Geraerts earned a 1-1 draw in the big match against fourth-placed Gent and remain second behind league leaders Genk. Union Saint-Gilloise have already qualified again for the championship play-offs between the top four clubs with 69 points from 32 games. The Yellow and Blues could take top spot in the remaining two league fixtures as they are only two points adrift from Genk. USG had a sensational season as a newly promoted club last term and they only lost to Club Brugge in the play-offs.
